General Nonimmigrant Visa

I just found out a couple of days back by my international advisor that I was out of status for two years now for taking classes in a community and transferring credits and it made me a part time student..He suggested I left the country after the semester and come back with the new I-20 and letter of recommendation he gives me. And I also I have been married to a US citizen for 2 months. Is it safe to go out of the country?

I am Canadian citizen & currently working on TN visa. My spouse is on J1 visa. I want to switch to J2 and get EAD. After couple of years he will apply for waiver and will move to H1. I believe I will be switched to H2 automatically as his dependant and my EAD will be void. Will that be possible at that time that I can switch back to my TN status?

I am working in a Federal Gov't Agency, and in the near future leaving for Frankfurt, Germany, for a conference, and with a plan in mind to fly to USA via Germany after my conference is completed.

2. If I have to travel out of the country , can I travel with my current H4 visa stamp ? or should I have to re-stamp it with my husband's new I-797 for new company ?
