Can you travel from Florida to Washington without a US passport?

Answer 1

No, you do not. Interstate travel in the United States can be done without a passport.

People of "the wrong color" have reported being detained at Immigration checkpoints along the Interstate. For them, a U.S. passport will facilitate travel.

Answer 2

Whether you are talking about Washington state or Washington, DC, the answer is the same. US citizens are not required to show a passport when traveling between states. To fly by plane, you are required to show ID, but that does not have to be a passport. In many jurisdictions, it is illegal to be in public without identification, but you can present identification other than a passport. Certainly, a drivers license or passport card are acceptable. Non-citizens are not required to present a passport when crossing state lines, but are required to have proof of legal presence in the United States if requested by an agent of Immigration and Customs Enforcement. This is particularly important when travelling within 70 miles of an international border, or when travelling into or out of a non-mainland state or U.S. territory (Alaska, Hawaii, Puerto Rico, Virgin Island, etc.).

Answer 3

It will depend from where you come to Florida, if it is from a different country you will need a passport.

Answer 4

Yes, but you must obtain a visa first.
