My brother is in his mid 20s and hasn't found a job, but that's not all....?

He's just graduated from Uni and can't find a permanent job (due to supply & demand reasons I suppose). His solution to that was to travel to Asia and because I would rather that he did something constructive, I paid for him to study at a language school+expenses. Having finished this course, he decided to do a bit of volunteer work at an orphanage, which is a good thing. I just found out that this orphanage has offerred to hire him and sponsor his working visa with a token monthly payment for his services-the catch being that he will need to raise US$4000 as a donation to them. He doesn't know what the money is for and is considering taking up the offer (though where he will find the money I do not know). I feel that my brother needs to face reality and go home to look for a job. I can't afford him and myself and to be honest, don't even want to have to deal with his dependence anymore. What is the best way to get him to go home, stand on his own two feet and find a job?

I found that in life one person cannot support another person, and that one person cannot become another person and take care of their life. Your brother has a hard lesson to learn and in time he will have to work 3 jobs to solve his past expenses as things will eventually catch up with him. On the other hand you need to learn to say "no". Otherwise you are supporting him and enabling him, and when you enable a person then they never learn. Sure it's fine to drop off some groceries once in a while, and if he was in a pinch and could pay all his rent except for $25 then sure you can pitch in. But continuously high amounts of money and not getting it back is just wrong.

If a company offers a working visa they don't ask for money in return, so something is either wrong with that organization or your brother is telling you that just so he can have $4,000 in his pocket (for whatever reason).

Today, and especially in the US, it's said that everyone who wants to be employed is now employed and so many jobs are out there not being taken. Believe me when I say that your brother can take a job for the present time if it pays less in income, he can take two to make up the salary between day and night employment or day and weekend employment.

You ask what is the best way to help him? Stop helping him and let him do it himself. Every time you have the money and get the urge to help him, just put that money into savings.

Dont help him financially. That will leave him no option but to come home. Be strong.
Tell him about your situation. And to make it clear, stop sending him money. He will get the message and will surely come home. Good luck!
search online, there are many places in asia esp that want foreign language teachers. tell this orphanage to take ahike. they want money thats it. if you search for teaching overseas you will fin dmnay resources that start at 30,000 a year. they pay for room, board, as long as he can give references from the oprhanage he should be in good shape and ifn a an easy job.
Stop financing his adventures. Your only giving him a reason to make an excuse.
Kudo's to you for helping your brother. You gone a bit past the helping part though and into making him a leech. Don't give him any more money. Set a date and let him know that that is the day the well runs dry. Do you REALLY expect him to stand on his own if you always hold him up? Good Luck!
I wouldnt do anything. Let it go and let him figure out his own life. Dont enable him by sending him any money. If he asks for it say no. Just let him figure things out for himself. As long as no one sends him money he will be forced to seek employment.
