Should I get a U.S. driver's license or state ID to help open financial accounts as a newcomer?

It helps a lot. Many banks and credit-card applications ask for a government-issued photo ID with a U.S. address, and a state driver's license or non-driver ID satisfies that cleanly, smoothing account opening and even some credit approvals. Requirements vary by state, but you'll typically need your passport, visa, I-94, proof of address, and often your SSN or an ineligibility letter if you don't qualify for one. Getting it early also establishes a paper trail tying you to a state, which matters for state tax residency. Until then, a passport plus visa usually works. Check your state DMV's requirements for noncitizens, and confirm bank ID rules before you go.
