Hello, I read a lot of topics regarding this issue but I'm still unsure about what to do. I'm going to usa in a few months under a j2 visa (My wife is a j1). My current employer is going to give me a job offer once I get the work permit (Multinational), so I was thinking into invest part of the salary into something. If they match my 401k contribution, can I make a withdrawal paying only a 10% for the penalty? I'm probably going to be there for two or three years, so it would be a good option to double my 401 contribution and take that back paying only 10%. Or should I take a look at a roth ira? Or both options are too complex and I should forget about this? Thanks

You WILL be allowed to invest in traditional IRAs, Roth IRAs and 401Ks if you are allowed to work, and doing so is probably a good idea.

If you make early withdrawals, you will pay a 10% Early Withdrawal Penalty PLUS pay normal taxes to both the IRS and the state where you live at the time of the distribution, so the tax rate will be a LOT higher than 10%.

However, determining which option is best for you goes beyond the scope of this forum, which deals exclusively with the TAX aspects of your situation. You should contact a local investment professional with experience with the various available pension options to determine which is the best course of action.
