Alaska Cruise (All US stops) expired H1 B stamp

[shankar_Muthu]

Hello everyone,
I had a question about immigration check at port of entry Seattle returning from an Alaskan Cruise with only US stops. This year due to covid all Alaskan cruises from Seattle will only do Alaskan stops without stopping in Canada. I was wondering if this would be considered as a domestic trip? Would there be an immigration check on the port of entry? The ship will sail through Canadian waters but will not stop at any Canadian ports.
If returning from Canadian waters will need an immigration check would Automatic Visa Revalidation apply? I have an expired H1B stamp and valid unexpired I-94 and recent paystubs from my employer. As this trip is less than 30 days and goes through Canadian waters would AVR apply in case there is an immigration check?

Thanks in advance!!
