My I94# in I797A H1B extension approval has 123456789 B (10 characters) whereas the I94 from online CBP has 123456789 B1 (11 characters). The lawyer in H1B petition missed adding the last digit and USCIS provided the approval notice with the I94 number indicated in the petition. I am going for stamping next month to India. Will this cause any issues with stamping and re entry to US? Lawyer says it should be fine and I can submit my online I94 at Dropbox and also at CBP at port of entry if asked about it but I am worried. Please help.
