Buenos Aires

A genuine strength. Buenos Aires has top-tier private hospitals expats rely on — Hospital Alemán (German Hospital, Barrio Norte), Hospital Italiano, and the Hospital Británico — all with international standards and bilingual, frequently overseas-trained doctors; English-speaking specialists are easy to find in the private system. Most foreign residents buy private cover ('prepaga') such as Swiss Medical, OSDE, or Hospital Alemán's own plan (basic tiers ~$75-280/mo, rising steeply with age). Private care means short waits, modern facilities, and costs well below the US; the parallel public system is universal and free but slower. World-class complex care is in-city — no need to fly out.

Humid subtropical with four real seasons (reversed from the US). Summers (Dec-Feb) are hot and sticky — January averages low-90s°F highs with 70-90% humidity and thunderstorms, so A/C matters. Winters (Jun-Aug) are mild but damp, ~46-58°F with chilly, poorly-heated interiors; frost is rare (a couple of mornings/yr). ~45 in rain/yr, spread year-round. Spring and autumn are the pleasant sweet spots.

Day-to-day, the upscale central barrios — Recoleta, Palermo (Soho/Hollywood), Belgrano, Puerto Madero — feel safe and walkable with police presence; violent crime against foreigners is uncommon and the homicide rate (~3-4/100k) is on par with mid-sized US cities, far below regional peers. The constant nuisance is petty crime: pickpocketing on the Subte and in crowds, bag-snatching, and 'motochorro' phone-grabs by thieves on motorbikes. Distraction scams and counterfeit-bill tricks target newcomers. Women report it manageable with normal big-city caution; keep phones out of sight and don't flash valuables. Argentina is US State Dept Level 1, with a Level 2 carve-out for Rosario (not BA).

A cosmopolitan capital with a sizeable, growing international presence, plus active Facebook groups, Internations meetups, and English-language services. English is fairly common in tourism, business, and among younger porteños and private-hospital doctors — but BA is a working Spanish-speaking metropolis, not a gringo bubble, so functional Spanish makes daily life far smoother. Easy to build a social life in English; harder to handle bureaucracy without Spanish.

Far south — the trade-off. Ezeiza (EZE) has US nonstops, but it's a long haul: Miami ~9h (American, LATAM, Aerolíneas Argentinas, daily), plus New York (American, Delta) and seasonal Houston (United, Jun-Aug). West Coast and most of the country require a connection via Miami, Houston, or São Paulo. Expect a full travel day each way and overnight red-eyes; not a place for frequent quick trips home.

Critical: there is NO US-Argentina tax treaty and no SS totalization agreement. Argentina taxes residents (broadly, permanent residents or those >12 months in-country) on worldwide income up to 35%, plus a 'Bienes Personales' wealth tax on worldwide assets above a high threshold. In practice it does not tax foreign SS, but foreign pensions/investment income can be taxable once you're a tax resident — and without a treaty you lean on the US foreign tax credit (Form 1116), not treaty relief, to avoid double taxation. Currency controls add complexity. US citizens still file with the IRS. Get cross-border tax advice before triggering residency.
