The Baht is getting stronger. I do not know the cause and do not like that. Went to the bank this morning and this month's deposit is 7,000 baht less than last month's.
I have received three new passports from the embassy. Then when I received them I won't to Immigration and they put the stamp on the new passport. you do not have to leave.
That is true. Have you noticed that every government hospital has a sign stating they will provide the medical first and deal with the payment later? Just what that means I am not sure. I have spent time in government hospitals and the 8 days for Dhingy Fever cost 22K Baht.
All you need to do is look at the paper that the immigration agent gave you. If the agent fails to give the paper then pay the charges and SUE the agent. The date issue is due to the agent's mishandling your account. Do not use an agent.
