US State Dept Travel Advisory
A foreign national or alien entering the US is generally required to present a passport and valid visa issued by a US Consular Official, unless they are a citizen of a country eligible for the Visa Waiver Program (VWP), or are a lawful permanent resident of the US or a citizen of Canada. The VWP allows foreign nationals from certain countries to be admitted to the US under limited conditions and for a limited time without obtaining a visa. The foreign national must arrive on an approved carrier (if coming by air or sea), stay no more than 90 days (for pleasure, medical purposes, and/or business), and be able to prove they are not inadmissible. The foreign national is still required to have a passport. To obtain a list of VWP-eligible countries and VWP passport requirements, please visit https://www.dhs.gov/visa-waiver-program. Note: all travelers transiting the US are subject to US customs and/or immigration laws.

Respect for family, community, and elders are major components of traditional Chamorro culture. Island culture has also been heavily influenced by both Spanish and American customs. The latter are pervasive in government and the media. Korean, Micronesian, Filipino, Chinese and Japanese immigrants have also enriched Guam's culture.
Tipping is common practice in the same way as it is in the US.
