You should ask this to a immigration lawyer or expert, this forum is IMHO not a good place for this question.I have an approval for b1/b2 visa.
from what i know the maximum stay in us with this visa, at each visit is 6 months.
is it possible to stay for longer than 6 months, for about another 2-3 months?
if yes, how do we do it?
anyone who has experienced this before, can you please shed some light on this matter?
or if anybody has any information regarding this and could please share it?
From my non-professional understanding of VISAS, yo should NOT stay longer than allowed. I don't think you will be deported or anything but future paper work, including renewal or soliciting new visas will probably be harder.
