H-4 Visa - status change from Korean citizen to Canadian citizen

[harirajmohan]

Hello @harirajmohan,

Would appreciate your insights in this case- I've H1B visa (stamp expired, cap exempt, few years left out of 6yrs) on Indian Passport, I also have B1 Visa (valid) on my Indian passport. Recently got my Canada Passport. I would be surrendering Indian passports (which has valid B1 stamp, and expired H1B stamp) to get OCI.

I plan to move to US using H1B Visa with my Canada passport with my current employer (who would file for GC), and also would want to retain B1 Visa from my Indian passport, would you know how to go about this and if this is possible?

As @Samoinp said, your canadian passport doesnt require stamped visa like B or H. You just need to travel using it for visit/work purpose. Also when you say, you are moving to US, then you dont/wont need B status. Your requirement is not clear.
Possibly i assume you are moving before surrendering Indian passport. If so then you should try to enter using Canadian passport as you would use the same for your gc, extension etc on same passport with uscis.
Either case, you wont require to retain any visas or worrying about it as you would end up using Canadian passport which doesnt require these visas.
