Recommendations For Us Visa Legal Advice

I have some questions I and/or my GF would like to discuss with a Thai immigration attorney about a US visa. Don’t need full service, have the applications, forms, supporting info etc. in what best I can tell is pretty close to complete state. There are some questions that we’d like to discuss with a professional, confidentially. Probably a one to two hour consultation.

Any recommendations for someone? Preferably in Bangkok who can speak Thai but US based (assuming knowledgeable) is possible. I don’t want a big retainer and don’t need a full-service A-Z service. Just want to have a consultation to clear up some questions.

Thanks for any help
