Hi Gang. I have a problem and would like some advice from my knowledgeable fellow forum members if you would please. For those of you who know me, know that I am wheelchair bound. I find that I am getting weaker and weaker. Presently if it were not for my life partner of some 23 + years lifting me into bed, car or into and out of the wheelchair, I would be stuck. I have had to close my business that I have had for some 25 + years and after having lived and loved my life in Thailand for over 30 years now find it necessary to go back to the USA. Here is the problem, I want to take my life partner with me and she wants to go but am finding it very difficult in getting a visa for her. Now you cannot even get into the consulate here. My question , does anyone have, or know of a reliable and reasonably priced visa agent that you can recommend? I know I am not as flexable and as able as I once was, so I do need your help please. Any help would be greatly appreciated. Thanks for reading gang.
