Nepaliguy,

As per USCIS , you must have completed the requirements for your Master's degree before

April 1st(the date of application) to be eligible for Master's quota. So if you can do this

then you can provide the letter from the Registrar's office implying that you have completed the

requirements set by the university and waiting for your diploma to be awarded in May.

I did the same, I got my diploma in May but i had completed the requirements before April, so I was

eligible for H1B this year.

and as per BikashKC, you also have the option to apply for general quota , but with minimal chances of

getting selected in lottery.

Anyway, Good Luck.
