took a friend there three weeks ago. Last time I was there and this time I noticed some people were being asked for a TM.30 receipt and others weren't, so I decided to ask why some were, and some weren't; the immigration officer stated that if someone is staying in a hotel, they ask for the receipt because, over the last year, there have been too many incidents where a TM.30 hasn't been filed.
Just go to Laksi IT Square and pick up the TM.7, STM.2 and acknowledgement of fines forms and fill them in, stick a passport photo of yourself to the TM.7 and put a phone number at the bottom, get a photocopy of your passport bio page and your entry stamp and give it to the immigration officer at desk 1. If you're staying in a hotel make sure you bring a copy of your TM.30 receipt, if you're staying in a condo you don't need a copy but make sure it has been filed.
Yes I am aware, because you are not married you have an additional requirement to meet, you have to obtain papers to prove you are the father which requires signed court documents as well as the 400k financial requirement. Unfortunately you cannot do it yourself and a lawyer must draw up the paperwork for you and submit it on your behalf, there is no way around this.
He doesn't say what his prior visa was all he states is "my baby was born 2 months ago and I have been on a non-o visa since then" based on that information alone it is clear he isn't on a non-o retirement and is on the last 30 days of his 90 day initial non-O visa.
Best thing I can suggest is talking to the US embassy to see if you can get that letter certified by them and then talking to the immigration office where you will be staying to see if they will accept that as an alternative.
it may very well be considerably higher than the requiremenr but it is up to the immigration office as to what documentation they will accept and as far as I am aware most if not all will only accept embassy affidavits as proof of month income.
