Legal Question in Immigration Law in Texas

Re: visa's

There is no set limit on how many times a person can enter the U.S. on a tourist visa. The most important thing is to either leave the U.S. before the visa expires, or renew the visa before it expires.

Re: visa's

There aren't any limitations on how often a Briton can visit the U.S. on either a B-2 visa or a visa waiver. If you entered on a B-2 for some reason, then you will be given a certain amount of time on the I-94 to complete your visit. If you enter on a visa waiver (green I-94), then you will have 90 days to complete your visit.

Usually if you apply and are granted a B-2 visa, it will be given for multiple entries and for several years, normally 5 or 10.
