Voluntary Departure with I-20 Visa

Hi everyone,
I attended university in the states where I met a lot of people. After my studies, I returned to visit my family and friends and ended up rekindling my love with my university sweetheart. We decided to get married and did so. We then filed for immigration while I was in the states. In the meantime, I learned that I was accepted in the Doctor of Pharmacy Program at the University where I completed my Pre-Med degree previously. The logical thing for me at the time was to accept the spot in the program which I did. Then, I was informed that I had missed my immigration date even though I did not receive the notice. I have had to hire a lawyer who is appealing the decision. However, since I still have not received status here, I requested and received a Student Visa I-20 which I now have. However, I have to return to Canada to have it sign by Boarder Officials. Immigration here has also request that I have something signed by the consulate office: I guess they want proof that I actually left the states. Do you think I will have a hard time getting back into the US with the I-20 that I have been granted-my wife will be with me at the Boarder- given that I had already overstayed my visit. I really do not need to immigrate to the US to live but I would at least like to finish Pharmacy school before I leave. Does anyone have any advice? Thanks in advance for your help.

Your post is a little unclear.

What exactly did you "file for immigration", and what "notice" did you expect to recieve.

Once married to a US citizen (I assume she is US citizen), you are no longer entitled to student visa, since you are assuming to be immigrating (which in you case is true). You need to complete the immigration process with your spouse, upto getting green card.

If you have been oversting in US, then you need to speak to a lawyer before setting foot outside US, or you risk being denied re-entry until you get GC.

In any event, the references to anything consular do not apply to you since you are Cdn. It has nothing to do with proving that you left. All non-Cdns need consular student visas. Cdns do not.
