I was arrested for smoking pot while living in a dorm at a university. I am a foreign student. I pleaded guilty and was fined. When applying for a new F1 Visa, I was granted a waiver as follows 212 SMALL D, 3, A, 1, WAIVER OF
212 A, 2, A, 2 GRANTED

I have now completed my university studies in Chemical Engineering and Physics.
I have applied for an OPT but still have not received any information. All that shows is, "adjusting students I-94.

Will this be a cause for denial for the OPT program?

Thank you for your reply

Yes it can, you should have consulted an attorney before pleading guilty without a plea agreement in place or understanding what could happen.

No one told me I should have done that. I was just being honest about the whole thing, no one even told me I should get a lawyer.
So what are my chances?
Can I apply for a master´s program if I get denied the OPT?
Thank you for your answer.
