will B-2 visa be canceled if.....

[humpydumpy]

i would like to ask if my B2 multiple visa be canceled by the uscis if i have a newly approved petition? you see my dad just became a citizen and he is planning on petitioning me. i am over 21 but never married. since it takes 15 to 20 years before my petition is processed i would like to visit him once a year. but i am worried that my B2 will be canceled or i will be refused entry in the u.s. if they found out i have an approved petition.what should i do?

It will be harder for you to re-apply for a visa later on... now that you have the visa, it is possible for you to visit him once a year. But when it comes time to renew this visa or to apply for another non-immigrant visa, you will have a harder time proving non-immigrant intent.
