It's not about the letter. The letter I can do it on the same day at the bank in the immigration. It's about the account printout with every transfer I did in the last 12 months. I can preorder yes, then they maybe accept it if it's not from the same day. But they also say the letter and the passbook have to be from the same day. This means: I have to transfer a small amount on that day, so the passbook shows the actual date but then the amount in the letter and passbook is not the same as in the account overview anymore. Could be a problem, I don't know.
