So, you've decided you want to get a visa to the US for your Thai wife... what you can expect to go through.
Let me first tell you, it's not a simple process as indicated on the US Embassy website. I'll attempt to go through the process as it was presented to me these past few months:
1. You must determine what type of visa you wish to obtain - there are many to choose from. On reading as much as i could gather from the website, I decided I would try for the K1/K2 Non-immigrant visa for my wife and 2 boys. My reason for choosing this type visa was, it would allow me to take my family to the US as non-immigrants and continue processing their immigrant visa after they have landed. It seemed the easiest and quickest way to get them there... when I presented my paperwork (extensive) to the 'powers that be', I was informed that this visa was not available for me because I am living in Thailand and this visa is only open to US Citizens who live in the States but their family or fiancee are in Thailand. This little bit of information was not shown on the website... so back to square one. I was told that the only immigrant visa I could apply for was the R-1 Immigrant Visa which would result in them obtaining a Green Card. OK, here we go.
2. It's not obvious but, after much searching I found that you must pass a qualification test via the Office of Homeland Security in the building across the street from the embassy in Bangkok. On the top floor of tower 2 (15th floor) is the Office of the United States Citizens and Immigration Services (USCIS) previously known as NIS (Naturalization and Immigration Services). There are a series of documents that must be presented which can all be found on their website (once you realize you need to go to that office). The cost of the USCIS document research is $375 per individual, in my case $1125, which of course is not refundable if found ineligible to go. I'm not sure of the amount of time it takes for your documents to go from USCIS to the Visa Section of the Embassy but in an attempt to speed things up, I included a handwritten letter indicating the job I was scheduled to take and the need for speed on their part. My documents were forwarded to the Visa Section the next day. Once you turn your papers over to USCIS there is nothing else you can do and they will notify you via postal mail at your home address. We submitted our papers on a Thursday and received our notice that they had been sent to the Visa Section the following Wednesday.
Now you just have to wait. There's nothing you can do and no one you can call or email. They WILL NOT RESPOND.
3. About 12-14 days later we received three large envelopes in the mail from the Embassy. Each one was addressed to each of the members requesting visas. The envelopes contained a series of documents which need to be completed and it also contained a letter indicating the number which identifies them for their 'interview'. When attending the interview, ALL paperwork MUST be completed. Some of the documents required were quite obvious - marriage contract, divorce papers, passports, name change papers, adoption papers (I had adopted both boys effective 30 Dec 08), employment letters, bank books, house papers (Blue Book/Yellow Book), Police clearance for anyone over 16 years old, etc. Everything you need will be identified but keep in mind - ANYTHING written in Thai must be translated and properly stamped by an acceptable translating agency. A FEW of the papers/documents identified in the large envelope(s) must be forwarded to the embassy via mail (we used EMS) and you are not supposed to forward these papers until you have collected ALL the other documents identified.
After submitting the papers, all you can do is WAIT... again.
4. Finally, you'll be notified by mail of your interview time and date and to bring everything you've already completed PLUS you will received some more papers which must be filled in and brought with you. In our case with 3 people, the size of the total package was considerable and my wife was more than overcompensating by bringing anything/everything she felt might be needed. When we arrived for the interview I was surprised to find out that I WAS NOT PERMITTED TO BE PRESENT DURING THE INTERVIEW. I had to find someplace to sit and have a coffee. I was allow to go in and pay the required fees for the visas though, $400 each for a total of $1200, again non-refundable if not granted. So, after paying the bucks, I found a coffee shop and waited from 9 to 11:30 when my wife called me over. The interviewer wanted to ask me a couple of questions. a. Why did I adopt the kids? b. Where were we going to stay in the States since I had no permanent address there? After the interview my wife was told she could pick up the visas some 7 days later - she just got them TODAY.
Total time involved for the process, approximately 16-18 weeks total (remember they sped it up for me); total costs for everything including four trips to Bangkok, fees for document translations, etc. - $2900; interviews were simple (for me) but were the cause of anxiety for the family; problems - only getting started and trying to interpret the websites, both USCIS and Embassy; suggestions - I cannot emphasize this enough, START EARLY and BE PATIENT.
GOOD LUCK
