Looking to get a US account for a trip I am planning. Would like to know which US Bank is in all US States and is easiest to deal with.

Will you have the proper Identification to open a US bank account?

I will have everything necessary... to my knowledge.

What is required?

If you are looking for accessibility for withdrawals, then Citibank is among the best. You can get money for free at any 7-11.

Otherwise, why would you be concerned about it?
