That's exactly what Bangkok Bank is doing. They've obviously had a gutful of being abused by visa agents, so they're simply doing what they have every right to do. It's far from blackmail. It's a condition of issuing a letter verifying an amount of money. If customers don't like it, they can simply move their business to another bank, which is most likely what Bangkok Bank is hoping
I guess so. I don't know. There was a guy posted on here last week complaining he had to drive 12 hours from somewhere up north to Pattaya to see his agent to get his extension. I guess a 24 hour round trip, hotel and fuel is no hassle, whereas an hour at your local immigration office is a hassle. People must have different viewpoints on "hassle". I use CW in Bangkok. It's about 30 mins to get there, about an hour to hour 15 actually there and 30 mins home. Cost is 1900 baht and about 120 baht for the train. Somehow I just don't see that as a "hassle"
A tourism visa is what she'd be seeking. The application is done online. What will be required is
(1) Statement of employment from her employer, stating years of service and salary
(2) Bank statements from previous 12 months
(3) Any land/property ownership documents
(4) Immediate family details
I do it every year for my lady. The first is probably the hardest, but with a good record of non-overstay it gets easier. In the last few years she's also had visas for UK three times and Schengen twice
