I'm planning on flying to L.A for a few days next month. However my current waiver will expire March 1st and I'm still waiting for my new one to come on. I submitted my package in August so I don't expect it to come in til March/April based on timelines provided here. I have return flight booking that shows I'm returning 4 days before my waiver expires. Would I receive much trouble at customs?
travelling with waiver that has only a week left before expiration
You can travel up until your waiver expires. Just make sure are out of the U.S. before it actually expires. So for example if your waiver is expiring on March 1st, you’d want to be out of the U.S. by February 29th to be safe.
