Advance Parole

Hello, recently assisted my daughter in law with her advance parole application. We are getting close to the three month mark (application received on November 8th). Was wanting to know if anyone has received AP and traveled into and back from Mexico using a land bridge entry. Seems like most people posting have traveled by air. I was wondering what the experience was like crossing back by bridge and if your passport was stamped with the new entry. She may have an opportunity to adjust status because my son (her husband) is a US citizen. I know she'll need to prove the legal entry to do so. Thank you for any feedback, great to see a site where folks are so supportive of each other.
