sure I hear what you are saying but someone earlier had said the price in NZ for the visa had gone up to $800 nzd that's $15,462 baht at today's rate. Would it cost you more or less in Thailand for an agent to complete it for you?
okay I understand what you are saying. I'm guessing it's the difference in cost to have it done in NZ prior to coming vs the lesser expensive option of hiring a visa agent once she gets here.
I query some of the comments and advice you are being given, that is why you are best to go through an agent so you will get the correct advice first time.
