I have my issue that my B1/b2 visa will expire in july but my parents live in US since the last six years and my mother had filed for the job based(h-1) immigration, currently the dates for it are July 2005 and the ours priority date is Jan 06, so its like 6 months in between. My parents have already filled for i-485 but now they want me in US to be with them so I plan to go there in June , with only 15 days before my visa expires. Will I get a 6 month entry or the entry till the visa is valid? Secondly how much time it takes more after the dates have arrived till I can change my status(file 485) on that basis or should I renew my visa before I leave(the only reason I am resistant to do it because security clearance from Pakistan can some times take ages). Your help will highly be appreciated.
