yes, today 2 Russians, new passports, just one Tourist Visa with one extension. Denied, after submitting two times.Monday and Tuesday, today afternoon they were told NO.
Go tomorrow to CW, to go on a trip to Chian Mai while on overstay will end up in in disater. You parents might arrested, locked up in prison, send to IDC. And deported and blacklisted.
you stayed over 90 days in the past 6 month, so Savannakhet will, most likely refuse a new Tourist Visa. Vientiane should be OK, but need a queue number. Avoid Phnom Penh. HCMC would be OK.
a transit visa can not be extended. It is good for 30days, but after you could do a border run, if you did not consume the 2 allowed yet or apply for a proper Non Immigrant Visa.
no, you did not understand, Savannakhet will deny you a Tourist Visa if you stayed in Thailand more than 90 days in the past 6 month, even under working visa. So you can border border run No1,than 30days at Immigration, than border run No2, than 30days. So you have around 4 month time to get paperwork together. Than can apply Non B in Vietiane or Savannakhet.
