A question. I have a non b plus a wp. My wife has a non o spousal visa. I have just changed schools and I need to change my visa to match my employment. As they're not ready with the paperwork for new visas our intention is to go to Laos for a TR 60 as an interim visa which can be changed at a later date. The visa officer at my new school that I need to cancel my non b at Chaeng Wattana prior to doing the visa run. Can't I just cancel at the Lao border?
