Tourist areas in major cities are generally safe. Gun violence is a reality — mass shootings occur. Some urban neighborhoods have high crime. National parks and rural tourist areas are very safe. Healthcare is extremely expensive without insurance.
Tap water is safe in most cities. Some rural areas and Flint, Michigan have had issues — check locally.
Gun violence is a unique risk. Healthcare costs can be devastating without insurance. Driving distances are massive — the US is huge. Natural disasters vary by region (hurricanes, tornadoes, earthquakes, wildfires).
Tipping is MANDATORY in practice. 18-20% at restaurants. $1-2 per drink at bars. 15-20% for taxis. $2-5 per night for hotel housekeeping. Not tipping is considered very rude.
Very casual. Americans dress down more than most countries. Jeans and sneakers are acceptable almost everywhere.
Christian majority but extremely diverse. Every religion represented. Very secular in daily life in most cities. Bible Belt (South) is more conservative.
