Can I use my application receipt if my passport doesn’t arrive on time ? I paid for it already but it’s currently still in process

Hi Claudia, no. A valid passport is required in order to cross through CBX.

They are very picky about those things. As a matter of fact, they held a lady when i was crossing because she was missing an actual passport

No need to have the passport

Based on previous experience if you don't have the current, valid document, is just like not having it. Again, that's my experience

I doubt it. Check with U.S embassy to confirm.
