My I751 got approved much much earlier than expected yesterday. I had planned to travel by land to Canada this weekend, leaving tomorrow and returning on Tuesday.
My approval letter says, "You should not travel outside the United States until you receive your new Green Card, as you may have difficulty reentering the United States. If an emergency arises and you have a need to travel outside the United States before you receive your Green Card, you may make an appointment at your local USCIS office to request an I-551 stamp in your passport that shows temporary evidence of status as a lawful permanent resident."
If I return to the border with my extension letter and expired green card, will CBP allow me to enter. I have no idea if I will be able to get the stamp today.
We have hotels booked and my mother in law is travelling to us today from NYC, and then we drive together tomorrow to Canada. So I really don't want to cancel the trip...
Would really like to hear from people in similar situation who successfully managed to return without the stamp...
