"Allowable number of border runs" is determined by the IO, the border, your nationality, current general feelings of the media and social channels, and possibly the weather. That one guy you talked to at that one border that one day may not be reflective of the experiences of others.
You should be able to show a statement from your investment account if your investment account is at a bank. I guess it depends on the officer. Worth a try, anyways…
Our muban has a lawn crew that work by appointment and will cut, bag, sweep, trim, and whatever else is needed in about 15-20 minutes for 500 baht. Depending on the amount of work you have for them to do, the crew varies up to 8 guys, and the work is very good. We have them over a couple of times a month. We have a cleaning lady we have used for years, and we use her twice a month for deep cleaning. We pay her 1000 baht per visit to cover her work and travel. Best to get here and try to sort it out once you have your living situation worked out.
Both are part of the green card process. K3 allows your wife to go to the US while the green card processes, the CR1 is issued abroad when the green card application has been approved.
The process requires an in person interview that needs to be scheduled, and the availability of appointments can vary. When my wife (then girlfriend) applied in 2019, it was around 6 weeks. Once approved, it only takes a week or so for the visa to be affixed and the passport to be sent via Thai Post. Best to start online by creating a profile and reviewing the requirements. It is pretty straightforward. If you feel like an agent can be helpful, you can contact one.
Just know, it can be really difficult to get a tourist visa for the US, but it is not impossible. Do some research and read through the forums for best practices and things to be aware of. There are a lot of Thai language Facebook groups where people share their experiences. I strongly suggest you have the person you are helping to search some of those out.
This is from a translation service website in Thailand:
Legalizing documents issued abroad and intended to be used in Thailand:
The first thing you’ll need to know is that the Ministry of Foreign Affairs in Thailand will only legalize documents in Thai or in English. If your document is in a different language, you will first have to have the document professionally translated and certified.
If you plan on using documents issued overseas in Thailand, you will need to have them legalized overseas before they can be used here. The process will eventually end at the Thai MFA, but the steps you’ll have to take in your home country will vary.
If you arrive in Thailand with a document notarized and legalized overseas by a Thai Embassy in your country, you will generally be able to submit this document directly at the Consular Department of the Thai MFA.
If you arrive in Thailand with a document notarized or legalized in your country by your own government, you will need to present it to your embassy in Thailand for authentication, then have it translated into English or Thai, then have the translation legalized by your embassy, and finally present the legalized translation and original to the MFA so that it can be legalized there and become usable in Thailand.
MFA requires that the documents be translated to Thai before they are certified.
It is also important to note, that foreign documents generally need to be certified by the Thai Embassy in the issuing country. The requirements will vary by country, but typically you will need a certified copy of the document (certified at the national level) from the issuing country. Once you have the Thai Embassy Certification, you can then have the document translated and certified by the MFA. In this use case, it may not require the home country certification, but you would have to make that inquiry with the MFA or an agency.
Thanya Park has an office with same day expedited service, or you can wait a few days and they will mail the passport to you. My wife had hers done there two weeks ago.
