If someone is undocumented in the country, can they still travel within the us?

Question

for instance, if say i want to travel from ca to tx do i have to clear customes or anything like that?

Answer 1

You can travel around...just avoid checkpoint areas near border states. Sorry for all the prejudice people....like they never break the law!

Answer 2

No such thing as undocumented, only illegal criminal aliens.

Sure let them travel around it increases the likelihood they will get caught and deported

Answer 3

Illegal aliens are not legally entitled to do ANYTHING in the US.  The answer is NO.

Answer 4

For domestic travel customs clearing is not required. Photo ID is all that is used for identity checks.
