Quick update : went today the IO. Had all docs handy. Only thing they asked me to fill out the TM 30 first to register my residence. Since I had a rental contract there was no need to ask the owner of my house. Went out after 50 minutes with my 30 days extension. Pretty cool. Thanks for all your input here.

one more question: we leave after two month to another neighbor country. Can I come back after a month and will get one more time a two month visa exempt?
