Change of status from B1/B2 to F1

[amirimtiaz]

I traveled on B1/B2 Visa (valid from FEB 2015 to FEB 2020) from Pakistan and did my change of status to F1 in 2016. I stayed in USA for more than 2.5 years and completed my MBA degree on 21 Dec 2019 and left USA at 28 Dec 2019. In this duration I was never out of status and never involved in any illegal activity. USCIS issued me change of status letter and there was no specific expiry date mentioned on that letter, it was Valid for Duration of Status.
Now my University Graduation Ceremony will be held on June 2019 and I want to attend that. I have some questions regarding such situation of mine.

1. Is my B1/B2 visa still valid after change of status to F1?
2. If my Visa is still valid, can Immigration officer refuse me to enter in USA?
3. If they will refuse me enter in USA, will they deport me and what will be the after effects on my travel again back to USA?
4. If in any case officer revoke my visa and deport me, can I apply for any other visa from Pakistan, like H1b or E2?
5. If Immigration refuse me to enter in USA, can I arrange some lawyer or any other help to get permission for entering at the time with immigration?

I just need some detail answers for all these my questions. I will be very thankful to you.

Whether the old B1/B2 is cancelled when you got the F1 is pretty much up to the consular office approved the F1. You should drop by the consulate and make sure you have a valid visa (either the old one is still valid or get a new one).

Just because the old one didn't expire doesn't mean it's valid. They can certainly refuse entry if they decide you do not hold a valid vis.
They can also refuse entry if they don't believe you are entering for valid purposes and intend to leave. Normally attending a graduation ceremony would be a no brainer, but your subsequent questions really have me worried about your REAL intent. Further, you don't just "apply" for an H-1B or E-2. If you think getting your F-1 was a bit of work, the supporting documentation and sponsorships for these other classes are even more so. If you're considering this, you should talk to an immigration attorney before you do anything (and possibly the proposed employer for the h-1b).
