Money and life on OPT: taxes, SSN, insurance, credit and housing

Practical guides for life on F-1 and OPT: filing taxes as a nonresident, getting an SSN, health insurance after graduation, building credit, renting, buying a car and banking.

Start with the tax filing guide, because your tax status can change after your first few years in the U.S. Then use the SSN and credit guides to set up your finances. The IRS and SSA are the official sources; these guides are general information, not tax advice.
