Join the Thai Visa Advice group on FB. The moderators there really know their stuff and take no crap or false information on the page. Follow Tod Daniels, Robert Lagas, James Miller, Ellie Takei and the others there. I learnt everything from them.
yeah I was just gonna post a reply saying almost the same. They need a good job with their own salary monthly into a bank a/c in their name. Letter from employer saying they still have a job when they return. Family, children, husband, wife etc. As many reasons as possible for them to come back to Thailand after the UK trip.
does she have a good job here with her own monthly salary in her bank book? Does she have many good reasons to come back here? Family house children job etc. Does she have a letter from her employer giving her time off and her job back when she returns. All that greatly increases her chances.
check out all the real estste agents and they will help u find one. There are many at the 2 or 3 million baht mark but they are very small about hotel room size!
