How to enter united states after ban has been served?

Question

if someone was barred from entering the united states and the time has expired from which they were to stay out of the united states will they still have to file a i-212/i-601 or will they just apply as usual

Answer 1

Well even if the ban has expired most of us would prefer that said banned person remain outside the US.

Answer 2

Waivers are used when the ban is in effect. Once the ban is expired, you are eligible to apply for visas the usual way again, so you may apply as usual as if you had never been banned and forget about I-212 or I-601.
