Brother,

Do you hold your MBA degree on hand or you're taking one class this Spring semester and will officially graduate in May this year?? To be able to apply for H1B you need to have your official degree/diploma in hand. If you are taking one more class this semester and will officially graduate or receive your degree in May, I am sorry that you would not be able to apply this April for H1B. However, if you hold an official MBA degree already, you can surely apply for it.

You can also either apply for H1B next April when you'll be in OPT or aply for H1B with your Bachelors degree in hand. For more information, consult an immigration attorney.

Good Luck!
