AP travel

Traveling to India in July for sister’s wedding – AP pending, re-entry concerns. Please help!

Hi everyone,

We’re in a bit of a stressful situation and would really appreciate guidance from those who’ve been through something similar.
Our situation:
• Husband filed I-485 based on EB-1A (approved I-140). He’s currently on H-1B.
• I am his derivative applicant, filed I-485 concurrently. I’m on H-4.
• Both of us have also filed I-131 (Advance Parole) and I-765 (EAD) as part of the package.
• AP is still pending for both of us.
The trip:
My sister’s wedding is in the first week of July and missing it is not an option for me. We’re hoping AP gets approved before then, but I’m anxious about what happens if timelines don’t work out.
My questions:
1. If AP is NOT approved before July, is there any way I can travel? (I have no valid H-4 stamp currently.)
2. If my I-485 gets approved while I am abroad, can I re-enter the US? I’ve read conflicting things — some say you’d need to go to a consulate, others say an approved I-485 means you’re a green card holder and can return?
3. If my husband’s I-485 gets approved while I’m in India (making him a green card holder), does that affect my derivative status or my ability to re-enter on H-4?
4. For those who’ve traveled on AP to India — any tips on the re-entry process? Did you face issues at the port of entry?
