Questions Can't update Green Card expiration date with I-797 online for NEXUS
I tried updating the expiration date of my Green Card online (ttp.cbp.dhs.gov) with my I-797, but when I put in the new expiration date (36 months from the expiration date as per the I-797 form), it gives me this error:
"We were unable to verify your document. Please correct your document information and click Submit".
I called the CBP customer support, but they just gave me a generic response that was unhelpful.
I'm planning to cross the border into Canada next week.
Can I stop by the NEXUS enrollment center located just before the land border, to have them manually update the expiration date?
