Hello,
I am a US citizen and about to sponsor my wife for US permanent residency. She is a Canadian Resident. The question I have is that my wife failed to return her i-94 the last time she left the US by land. She then re-enter the US (by land) with the same I-94. In this case I do not know which date to put on the applications, i-130 & i-485. Should I put the date when her last entry to the US was recorded (July 07), or the one when she entered for the last time using the same I-94 (August 07)? PLease help. I called Immigration and they said that the last Arrival date must match that of the i-94. If I put July 07, would Immigration know that she left end re-entered on August 07 with the same I-94?
Thanks.
