<prompt> Human: I recently took a job in the Central Pacific doing engineering work. I make about 50,000 a year here. It was a very substantial pay cut, but heres the kicker: No state or federal income tax Rent, utilities, and food paid for No cost for fuel or vehicle maintenanceId like to make the best of this situation, Ill be here for at least two years, and would like to go home with a little saved up. I pay about 5 to a host-nation tax, and social security, I have about 95 of my annaul income available to me.I only have a small amount of personal debt. Maybe 2,500 between credit cards and other debt from back home, should have this paid off within the next couple of pay checks. I have about 10,000 in an old company sponsored 401k.Contributing 10 to a Roth 401k, 5 company match currently. I have a Fidelity brokerage account, and would like to further invest in mutual funds. I like the Roth option, because Im not being taxed on my income, and the investment can grow tax-free, if I understand that correctly. I would really like to make the most of my 0 tax rate.How would you best use this opportunity? I am not interested in buying expensive toys, my sole focus outside of work is putting myself in a comfortable financial position to return to the States for work eventually. Id like to get my retirement on track. Im in my mid-twenties, and would like to get going as early as possible. Thanks fellas!  <response>: Contributing 10 to a Roth 401k, 5 company match currently.

Check with a CPA to make sure this income qualifies.After you pay off your debts, chop up your paycheck via direct deposit to go where you want it to. Most employers will allow you to chop up a check into 3 pieces. X spending money - you wont need much - X savings
