Can you be asked to produce any of the 3 of's upon re-entry for this type of visa ? 20k cash, proof of residence or onward ticket ? Can immigration insist you spend at least one night out of the country ? Heard some Thai/Malay border points can be "difficult" if they want to make a point
Are you legally required to cancel it ? Surely if you leave without a re-entry permit that immediately cancels it on exit. Or if there is even a remote chance of returning buy a single re-entry permit for 1000 baht , if you come back before expiry - no visa required. If you don't it runs its allotted time and expires naturally
Recently changed ? Had 2 back to backs from UK but didn't go home in November so just extended thru immigration , not a problem but a pain in the ass. Letter from Embassy, photos not good enough , home visits & reams of paperwork. How long before Laos follow suit ?
