While I lost my job, I've applied for I-539 and left the country in a month. While I got my new TN I was told by the border officer that the I-539 application is no more valid as I've already left the country and I don't have to do anything. I was notified by email from USCIS that my I-539 is denied and the notice would tell me about the options. Is there anyone experienced this situation and what should I do at this point?
