No. of years I can stay in US, if I transfer my Visa from L1-B to H1-B

Hello,

I am having L1-B Visa and currently in USA for 3 years. If I get my Visa transfered to H1-B, what will be my stay period? Still how many years I can stay in USA?

You can stay maximum of 6 years (L1-B + H1-B visa combined), so you can stay 3 more years in H1-B. If your employer do Green Card processing, then you can stay beyond 6 years.
