I have an r1 visa from April 2008 until April 2013. I am out of the USA right now. I want to return in March 2013 to continue missionary work. But I must leave before the r1 expires on April 27th 2013, is that right? how can I renew the religious visa or is it not possible? can I get another r1 visa? I think when I applied I got the r1 visa under old rules and so much paperwork was not needed. Can I apply for extension? Can I apply for green card right now?
