I have a question. Can I renew my unexpired J1 visa? My j1 visa was issued for 1 year duration. I plan to take a short trip out of the US in July but I want to renew my visa this May in canada (before my J1 visa expires. My J1 visa expires in June). Is this allowed (renewing before j1 visa expiration)? I have updated paperwork including DS-2019. Anybody has done this before or any ideas? Thanks.
