Can I apply to extend my H1B, irrespective of whichever the employer is?

USA H1B Visa
1

Can I apply individually to extend my H1B Visa, after it expires, irrespective of whichever the employer is, and whether I get any sponsor or not ?

I have NEVER been in US, in my whole H1 B cycle. Can i apply for H1 extension saying that the visa duration was not completely utilised, on my own?



 



Thanks,
