Mine has an inside kitchen with cooker, hob, microwave and dishwasher, as well as an outside kitchen with a washing machine. Even the condo I stayed in at first had a hob and washing machine.
A Thai visa agent can't guarantee you a visa for the USA. All they can do is organise the proof that you have to provide anyway, so you would be wasting your money. They can't bribe someone in the usa to guarantee success.
Get your proof (lots of it) organised, cover everything requested by immigration, with each document numbered and a list of all the documents. Then submit it yourself. If your proof is badly organised or missing, the chances are they will reject the application.
are these agents from the UK? if not why pay a Thai person to do a UK process?
Is there a guaranteed pass or no fee?
I don't understand why anyone would use an agent for this task, surely it's just a case of organising and providing the evidence the UK government request.
If they have insufficient evidence the agent can't bribe someone in the UK to approve it.
I have 2 accounts, one with the 800k deposit and a separate account for daily living expenses. It means there's no chance of me going below the visa threshold and makes it simpler to print the statement every year.
