Do us citizens need a passport to travel from state to state?

Answer 1

Not necessarily, it is not necessary to have your passport when you travel dometic however, you can always bring it as a form of identification for the airline or the transportation of which you will be using for the travel.

Answer 2

No. There are no restrictions on visitors to the US traveling between states. In fact generally the only thing that marks the boards between states is a "welcome to [state]" sign next to the road.

No, but it is no longer wise to do so.

A Non-US Citizen who is legally in the United States (either as a visitor, LPR (Legal Permanent Resident) or holder of some other valid visa) can travel freely from State-to-State without a passport.

HOWEVER, it is always wise to have with you as some States who are seeing a rise in anti-immigrant sentiment (most notably Arizona, Iowa and, as of January 2011, Maine) either require or authorize authorities to inquire as to Immigration status. So if you are pulled-over or otherwise detained by authorities you may be required to produce this documentation.

If your Passport is expired but your US Visa is still valid (most commonly in cases of LPRs where the 10-year Green Card Expiry exceeds the validity of their national passport) you would be wise to renew your passport but, at least, ensure your Green Card is with you.

Answer 3

The US has no internal passport.

Not technically, but it is no longer wise to travel without a valid passport or - at least - your Green Card.

A Non-US Citizen who is legally in the United States (either as a visitor, LPR (Legal Permanent Resident) or holder of some other valid visa) can travel freely from State-to-State without a passport.

If you have a US drivers license, your citizenship has been verified. Coupled with a Green Card or visa, you should have no issues if you are stopped. This is not really a change from the past, but new laws have come into effect.

Answer 4

If you are visiting the US from Another Country, you can travel within the US without having to present your passport because there really are no border checkpoints between states. However, if you are stopped by the police it is a good thing to have.

Answer 5

When a US citizen travels from state to state, you will only need a valid government issued photo ID. Your passport is one perfect example of this so you can bring it but not absolutely necessary if you have other valid identification like your license or your State ID.

Answer 6

In Australia, no. You will need photo ID or a medicare care card or similar for a child.

Answer 7

If you are a US citizen you can fly to another US state without a passport.
