Miami Federal Investigation Attorney
A federal investigation in Miami-Dade County often runs for months or years before the person at its center hears a word about it, and by then agents may already hold bank records, phone extractions, and recorded conversations. The Law Office of Nayib Hassan, P.A. represents business owners, executives, professionals, and individuals under federal scrutiny in Miami, Miami-Dade County, and across South Florida, and the firm works with a Miami federal investigation attorney mindset: the best time to build a defense is before a charging document exists.
Investigations in the Southern District of Florida can arrive in several forms. A grand jury subpoena may land at a business. A target letter may reach a home. Agents from the FBI, IRS Criminal Investigation, Homeland Security Investigations, the DEA, or an inspector general’s office may knock on a door and ask for “just a few minutes.” A bank may freeze an account without explanation, or a device may be seized during a search. Each of these is a different posture, and the right response to one can be exactly the wrong response to another.
What happens in this window matters more than most people realize. Before an indictment is returned, there may still be room to present information to prosecutors, to shape which charges are brought, to arrange a voluntary surrender in place of an arrest, and to protect assets that have no connection to any alleged offense. Once the grand jury votes, many of those options narrow or vanish.
How Federal Investigations Unfold in Miami-Dade
Federal cases in Miami follow a rhythm that differs from state prosecutions. The investigative phase is controlled by agents and an Assistant United States Attorney, with no judge supervising day to day. Prosecutors use grand jury subpoenas to compel documents and testimony, search warrants to seize records and devices, and cooperating witnesses to explain what the paper trail means. Many of those witnesses are people who were themselves exposed and decided to talk.
The person under investigation usually occupies one of three roles. A witness is someone prosecutors believe has information but is not suspected of wrongdoing. A subject is someone whose conduct falls within the scope of the investigation. A target is someone the government believes it has substantial evidence against. These labels can shift, and a person who starts as a witness can become a subject after one poorly considered interview. Learning which category applies, and whether it is changing, is one of the first things a lawyer does.
The investigation ends in one of a few ways. Prosecutors may decline to charge. They may offer a resolution before indictment, such as a negotiated information or a cooperation arrangement. Or they may present the case to a grand jury and obtain an indictment, after which the matter moves to the federal courthouses in downtown Miami and a different set of rules governs. Cases in the Southern District are heard in Miami, Fort Lauderdale, West Palm Beach, Key West, and Fort Pierce, and appeals go to the Eleventh Circuit.

For investigation-stage clients, a few things stand out. Mr. Hassan has represented defendants in multi-defendant drug cases, including matters where charges were dismissed and one where his client received one of the lowest sentences among all codefendants. He is fluent in Spanish and speaks directly with clients and their families without an interpreter. The firm intentionally limits its caseload so the attorney handling your matter is the attorney you talk to, and it is available 24 hours a day, 7 days a week, because agents do not keep office hours. Consultations are confidential.
Federal Investigations Our Miami Defense Attorney Handles
- White Collar and Federal Fraud: Wire fraud, mail fraud, bank fraud, securities fraud, bribery, and false statements to agents. These investigations usually rest on subpoenaed financial records and turn on intent and on how the government calculates loss.
- Money Laundering: Investigations under 18 U.S.C. 1956 and 1957, often attached to fraud, drug, or international trade inquiries. Movement of money between accounts, through real estate, or across borders can draw scrutiny even when the source was lawful, and structuring cash deposits to avoid bank reporting is part of this work.
- PPP, EIDL, and SBA Loan Fraud: Pandemic-era loans remain open to prosecution because Congress extended the limitations period to 10 years. Inquiries often begin with an SBA or lender audit and can lead to wire fraud, bank fraud, false statement, and aggravated identity theft allegations.
- Healthcare and Medicare Fraud: Physicians, pharmacy owners, clinic operators, home health agencies, equipment suppliers, laboratories, and billing staff may be investigated over billing practices, referral arrangements, or kickbacks involving Medicare, Medicaid, and private insurers.
- Bulk Cash Smuggling and Currency Reporting: Travelers through Miami International Airport and PortMiami who carry more than $10,000 must report it. Concealment can lead to seizure and charges under 31 U.S.C. 5332 even when the money was legitimate.
- Federal Drug Conspiracy: Wiretap-driven inquiries, maritime interdictions, and large multi-defendant conspiracies where early decisions about cooperation and exposure shape everything that follows.
- Tax, Identity Theft, and Credit Card Fraud: IRS Criminal Investigation and Secret Service inquiries that frequently begin with document requests or agent interviews.
- Asset Forfeiture: Seizures of money, real estate, vehicles, and business assets, which the firm fights alongside the criminal matter.
What to Do When Federal Agents Contact You or Your Business
The first rule is to stay polite and say little. You are not required to answer questions about an investigation, and anything you say can be used against you. A false or incomplete answer to a federal agent can itself become a separate false statements charge, which means an interview meant to “clear things up” can create a new problem. Ask for the agent’s name, agency, and contact information, say that you will have a lawyer follow up, and then call one before you do anything else. The same applies if agents show up at your workplace; employees generally should not volunteer documents or opinions without guidance.
If you receive a grand jury subpoena, do not ignore it and do not start deleting, editing, or reorganizing files. Destroying or altering records after learning of an investigation can be charged as obstruction of justice, and it is frequently a worse problem than the underlying conduct. Preserve everything, including emails, text messages, messaging apps, accounting files, and phone backups. Gather the subpoena, any envelope or cover letter, and a written note of who delivered it and when. A lawyer can then assess what is actually being requested, whether the return date can be extended, and whether any privilege applies.
A target letter calls for the same urgency. It means a grand jury is looking at you and prosecutors believe they have substantial evidence, but it can also be the moment when a lawyer has the most room to act, whether by opening a dialogue with the assigned Assistant United States Attorney, presenting a defense narrative, or negotiating the terms of a surrender. If your bank account has been frozen or agents have searched your home, write down what was taken and what paperwork you were handed, and avoid discussing the search with family members or coworkers who could later be asked about it.
If charges do follow, the case moves into the Southern District of Florida, where Miami matters are heard at the federal courthouses in downtown Miami. Initial appearances and detention hearings come first, then discovery, motions, and either a negotiated resolution or trial. Cases tied to Broward, Palm Beach, or Monroe County can be heard in the Fort Lauderdale, West Palm Beach, or Key West divisions. Getting a lawyer involved before this point is what allows a surrender to be arranged calmly instead of an arrest occurring at dawn.
Common Mistakes That Damage Federal Investigations Early
The most damaging errors tend to be the most understandable ones. People agree to an interview because they believe honesty will end the inquiry, only to discover that an imprecise recollection is treated as a lie. Business owners contact employees or partners to “get our stories straight,” which can look like witness tampering or obstruction. Individuals move money or transfer property to protect it, which can read as concealment and may support additional money laundering or forfeiture theories. Others assume an investigation is only about someone else and wait, losing the chance to present their own side before charging decisions are made.
Another recurring problem is treating a civil or regulatory inquiry as separate from the criminal risk. An SBA audit, a lender inquiry, or a Medicare billing review can be the visible edge of a parallel criminal case. Responses to those requests can end up in a prosecutor’s file. Before sending anything to a lender, agency, or auditor, it makes sense to understand whether a criminal investigator may be reading over their shoulder.
Frequently Asked Questions About Federal Investigations in Miami
Do I have to talk to federal agents if they come to my home or business?
No. You may decline to answer questions and ask the agents to speak with your lawyer. Being courteous while declining is the safest approach, because statements to agents can be used against you and inaccurate answers can lead to a false statements charge.
What is the difference between a witness, a subject, and a target?
A witness is believed to have information but is not suspected of misconduct. A subject’s conduct falls within the scope of the investigation. A target is someone prosecutors believe they have substantial evidence against. These designations can change, which is why an attorney helps clarify where you stand and whether that status is shifting.
What should I do if I receive a grand jury subpoena?
Preserve all records and do not alter or delete anything. Contact a federal defense lawyer promptly so the scope and return date can be reviewed. A subpoena does not by itself mean you are a target, but how you respond can affect how prosecutors view you.
Can I be investigated for PPP or EIDL fraud years after receiving the loan?
Yes. Congress extended the limitations period for PPP and EIDL fraud to 10 years, so loans from the pandemic period remain open to prosecution for a long time. If a lender, the SBA, or an agent has contacted you, get advice before responding.
Is carrying more than $10,000 in cash while traveling illegal?
Carrying it is not illegal, but amounts over $10,000 must be reported when entering or leaving the United States. Failing to report, and especially concealing the money, can lead to seizure and charges such as bulk cash smuggling.
Can a lawyer really change the outcome before charges are filed?
Often an attorney can influence the process. Before an indictment, there may be an opportunity to present information to prosecutors, discuss the scope of charges, negotiate a voluntary surrender, or protect assets unrelated to any alleged offense. Those options usually narrow once a grand jury returns an indictment.
How long does a federal investigation last?
There is no fixed timeline. Some inquiries resolve in months and others continue for years, particularly when they involve voluminous financial records, multiple agencies, or conduct spanning several countries. Quiet periods do not necessarily mean the matter is closed.
Can agents seize my bank account or property before I am charged?
Yes. Federal law allows seizure of funds, real estate, vehicles, and business assets tied to alleged offenses, sometimes before any charge is filed. Forfeiture can proceed alongside or separately from the criminal case, and challenging it early can matter for a family or business trying to keep operating.
Should I hire a lawyer if I think I am only a witness?
Often yes. A person who starts as a witness can become a subject after an interview or document production, and a lawyer can attend or arrange interviews, negotiate the terms of cooperation, and watch for signs that your status is changing.
Does the firm handle matters that involve other countries?
Yes. The firm’s practice includes matters involving Colombia, Mexico, the Bahamas, Ecuador, and Cuba, and it represents clients in federal courts across the country. Mr. Hassan also speaks Spanish with clients and families directly.
Can I speak with a lawyer outside normal business hours?
Yes. The firm is available 24 hours a day, 7 days a week, since searches, arrests, and agent visits do not follow a schedule.
