Re: Immigration question...
roman
my aunt had petitioned for my parents and they have been coming to US on visit visas throughout. even after the petition, the only time its recommended thatthey dont travel is when there case is up and in process i.e. theya re waiting for the interview and everything else is done.
its not unique for UK citizens as my sisters inlaws were in a similar situation and they did the same throughout the time from when the petition was filed to when the interview letter came. they travelled on Pak passports.
