you could be right, its a long time ago for but I do recall I had to prove my income Apr to sponsor,then it was only £18,600 now it's 27k+ and soon going up again.
that's right but not at the embassy it's at trendy house sukhumvit soi 13 bangkok.plus he will need to show proof of annual earnings which now 27k is needed to be a sponsor.
it's upto the individual to make their mind up what they want to pay,if they get what they want for whatever it costs it's their choice so it doesn't matter
