If you have been placed in removal proceedings, the first hearing is called a master calendar hearing. It is not a trial. It is the hearing where the court confirms who you are, what the government says you did, and what relief you intend to apply for.
Where it happens
Tennessee has one immigration court and it is in Memphis, so cases from across the state, including Nashville and Middle Tennessee, are heard there. A good deal of the docket now runs by internet-based video, and whether you appear in person or on a screen depends on the judge and the hearing. Your notice is the authority. Read it, and check the court's own status page before travelling.
What actually happens
The judge takes your pleadings to the charges in the Notice to Appear, sets the language you will proceed in, confirms your address, and sets deadlines. If you have an attorney, most of this is handled for you in a few minutes. If you do not, the judge will usually give you time to find one, once.
Nothing is decided about whether you can stay. That comes later, at an individual hearing, which is the one that looks like a trial and often takes a year or more to arrive.
The two mistakes that cost the most
The first is not appearing. A person who does not show up can be ordered removed in their absence, and undoing that order is far harder than attending would have been.
The second is not updating your address with the court. Notices go to the address the court has. If you move and do not file the change, the notice of your next hearing goes to the old address, you miss the hearing, and the first mistake happens by accident.
What to bring
Every document the government has given you, including envelopes, because the dates on them matter. Identity documents. Anything showing how long you have been in the United States, your family ties, your work history, and any medical or hardship circumstances. Do not filter it for what you think is relevant: eligibility for relief often turns on facts people assume are unimportant.
Getting advice early is not optional here
Relief in immigration court is technical and deadline-driven, and some of it is lost simply by the passage of time. If there is any question you might be eligible for something, that question is worth asking before the next hearing rather than after it.
