Navigating the U.S. immigration system involves many important steps. Whether you're applying for citizenship, renewing a green card or DACA, proving good moral character, showing your time in the U.S., attending a biometrics appointment, confirming citizenship through a parent, traveling with advance parole, or applying for a religious worker visa—this guide helps you understand what to expect, what documents to gather, and how an immigration attorney can support you every step of the way.
Most green card applicants must complete a medical exam with a USCIS-approved civil surgeon. This guide explains how to prepare, where to go, and what to bring. As of 2025, medical exams are valid only for the immigration benefit application they’re submitted with—they no longer remain valid indefinitely.
If you're from a Visa Waiver Program country, you can visit the U.S. for up to 90 days without a visa—but there are strict limits. You can’t extend your stay, change your immigration status, or work. If you overstay or try to adjust status, you could face serious immigration consequences.
