I am wondering where the OP is. She has disappeared after posting her concerns and question.

To the OP: The fact that your financial responsibility for your mom is $1200 a month (about nearly 40,000 BHT), it makes me curious about the type of job you do for a lviing in Thailand. You must make a huge amount of money. If your mom needs that money each month for all expenses, she must either live her luxurious life (having a nice big house, nice clothes, and a nice car), take care of other family members financially (e.g., some or all your siblings, their children), or is well-off herself but still expects you to support her financially.

And if you make that much money, you should have some saving that can help your mom while you are waiting for the EAD here/until you get a job.

And if your mom is well-off herself, she shouldn't need that kind of big support from you.

Even though many people here see this issue as culture related, I do not.

I hope you the best.

Thanks for everyone for all your advice. It's very helpful.

Now I'm working as Sales and Marketing director here in BKK Company, and I can make around $2200 per month. Since I’ve been to work only for 2years, and now I’m just 25. So I got a small saving but I don’t think that it’s enough to pay my things if I were there. And you know every family is difference, my mom too. Since I’m the only one child, I’m the only one who supported her for everything and whatever reason since I got a job. You know it’s hard for me either to just leave everything behind to her, and It hurts me so bad too if I have to pass this to him. I don’t want it to be like this. I do love him and I know how much he hurts from this.

If I still get a chance to go there, I plan to sell my car and some of my property here. Atleast I can help him to pay for my expense here while I’m waiting for a work permit thing. I hope this would help him. But even now he hasn’t contact me back almost 2weeks. I'm sooo depressed and hopeless.

Thanks for everyone for all your help and advices. Please pray for us!!

I suggest you apologize for your unreasonable request and offer to delay your arrival until you can arrange to provide the bulk of your mother's needs yourself. If it takes a few months of frugal living and liqudation of some assets to do so, so be it. If your mother's life style were to be adjusted to something comfortable, yet more reasonable, that could speed the process as well.
