It largely depends on the actual visa your colleague is one. I suggest you learn more about his situation - it might be informative in understanding his worldview. If he's on an H-1B there's only one thing you can do for this particular coworker. Help him prepare for interviews and get a better job offer. He should be able to have his work visa transferred over to the new company in 5-6 weeks. There's no reason he can't ask for a raise too. I've done it, on an H-1B, and sometimes I've gotten it. No one's going to fire a good performer for asking for a raise, especially if the job market is good. But some people find that too confrontational - getting a better offer is easier, in that case. (BTW, if the company is underpaying him, I'd encourage you to shop around a bit too. Maybe you aren't at market rate either?) If he's on an L1 visa (i.e. transferred from an overseas branch of your company, rather than being hired directly) then I don't know if there's much you personally can do for him. He has to find a new job that pays more money, applies for an H-1B for him, and is willing to wait until October, which is when it starts. Or he can ask for a raise - see above. If he has an I-140 in process, it's possible he wants to stick around until that's done (although what's the rush really? Indians applying today won't get a green card for 40+ years at current rates). If the company isn't doing that for him, or if it's already done, he has no real reason to stay.
