Removal proceeding under section 240...

Since you are no longer removable, you can terminate immigration court proceedings. However, you may have an order of removal in absentia pending, since it's possible that you missed your court hearing. You need to call 1-800-898-7180 end enter your A# to confirm your court related status. If, in fact, your order of removal was issued, you would need to retain an immigration counsel to file a motion to reopen and terminate your proceedings to vacate the removal order. However, it might be challenging to prove that you had a valid reason (lack of notice, medical issues, etc.) to have missed a court hearing. There is also a chance that court has not set the hearing for you as of yet. This is a much better scenario, because then your attorney would only need to terminate proceedings, since they may be still ongoing. A third scenario is that you (or your attorney) can request ICE Office of District counsel to withdraw the NTA based on you attaining a lawful permanent status. In any of these three scenarios my advice would be: do not attempt to do it yourself. Please hire a qualified attorney to help you. Good luck!
