Health Insurance
Health insurance is strongly recommended but not required for entry. Medical care in the United States is extremely expensive without insurance. Visitors should obtain comprehensive travel health insurance that covers medical treatment, hospitalization, and medical evacuation. Medicare and foreign health insurance typically do not cover care in the U.S. Emergency rooms must treat emergencies regardless of ability to pay, but you will receive bills afterward.
Protect Your Trip with Travel Insurance
Comprehensive coverage for medical emergencies, trip cancellation, lost luggage, and 24/7 emergency assistance. Many countries recommend or require travel insurance.

Tourist visas (B-2) and VWP entries cannot be extended beyond initial authorization in most cases. VWP stays (90 days) are absolutely non-extendable. B-2 visa holders may apply for extension with USCIS using Form I-539 before current status expires - approval not guaranteed. For longer stays, must apply for appropriate visa type: F-1 (student), J-1 (exchange), H-1B (work), etc. from outside U.S. Overstaying visa results in future entry bans (3-10 years depending on overstay length). Working on tourist visa is illegal and grounds for deportation and permanent ban.
B-1 visa or VWP allowed for business activities: meetings, conferences, negotiations, consulting with business associates. Cannot receive U.S.-source salary or engage in productive employment. Bring invitation letter from U.S. company, conference registration, or business documents.

Must enter U.S. using U.S. passport if you're a U.S. citizen, even if holding another citizenship. Cannot use foreign passport for entry if U.S. citizen. Dual citizens should carry both passports when traveling internationally.
Previous visa overstays, deportations, or immigration violations may result in entry bans (temporary or permanent). Must apply for waiver of inadmissibility if banned. ESTA will likely be denied - must apply for visa at embassy. Be truthful on applications - false statements result in permanent ban.
Criminal convictions may make you inadmissible to U.S. Crimes involving moral turpitude, drug offenses, and multiple convictions are particularly serious. Must disclose on visa application. May require waiver. ESTA may be denied. Consult immigration attorney if you have criminal history.
