do u know if when traveling inside the USA if u need ur passport or any other documentation other than a i.d?

after 9/11 you definantely need everything.

If you're a citizen of the USA and you're travelling about, then all you need is a valid form of ID. If you're not a citizen then have your passport, visa, and every document you can transport to make life easy on you.

when in foreign country yur passport is your only id. so carry it. your country's id is not recognised.....passport shows that u're not alien

are u traveling into the USA or just from state to state....if just state from state you dont need a passport just ur id will do. im not sure if u need a birth certificate or not .. if u are traveling into the usa or out of the usa then u need a passport... try going to this website... http://www.travel.state.gov

Once your In, it's wise to keep the information nearby, but you're not likely to need it, If you have citizenship, screw it and just carry an Id.

As of today's date you only need a I.D.Who knows when we will need a passport in our own country/ I fear the day is coming soon.

If your not a citizen, yes. But you always need identification there are laws that say they can detain you until they find out who you are.

U.S. citizens are not required to carry anything within the U.S. unless you are driving a car, then you need to carry your driver's license. Obviously, any form of good identification SHOULD be carried in case of emergency, and it does make your life easier in so many ways. Especially if you want to cash a check where they do not know you, etc.

Lawful permanent residents over the age of 18 are required to carry their I-551 (green card) at all times.

Any other LEGAL aliens must produce evidence of status upon demand by legitimate law enforcement officials. The easiest way to comply here is to have it available at all times though it is not REQUIRED that it be carried. An example here is a visitor with passport, visa and I-94 form.

Then, there are the ILLEGALS... Since they are not accustomed to obeying the law, do not expect them to have any identification at all. If they do, it should not be implied that it is genuine. It cannot and should not be trusted.

Im not a US citizen and I travel withing the USA just with a goverment ID, a license will be good !!
