H1-B Visa Filing Requirement - working outside of US

Can an employer file a H1-b visa for a person when he or she is working remotely from a different country ?

Yes, they can. You need to get stamping after you get approval to go to US and work there.

Thanks a lot Kumar for your answer. Just one last question, can the stamping be done in USA from where I am planning to remotely work if I am working for an Indian MNC which files my H1-B.
