Ok, what happens if we get it, (the stamp) then go over to the US - but for a vacation before the final move close to the 6 month limit - & get the green card...? Would it make the IO question us on our final move (past the 6 month mark) as to why we didn't complete the process which would, it turn, make things difficult for us? BTW, we have no plans to do this yet, just thinking in advance, perhaps years down the road - but wondered how logistically people do it!?
