North America (USA)
A visa is issued by a U.S. Embassy or Consulate. A visa entitles the holder to travel to the United States and apply for admission; it does not guarantee entry. An immigration official at the port of entry determines the visa holder’s eligibility for admission into the United States.
The purpose of your intended travel and other facts will determine what type of visa is required under U.S. immigration law. As a visa applicant, you will need to establish that you meet all requirements to receive the category of visa for which you are applying. Visitors from the UK travelling to the US for up to 3 months should apply for an ESTA. For more information and to apply, visit https://esta.cbp.dhs.gov/esta/
If you have a UK passport (or any other EU passport) then the situation with visas for South America is very simple: you do not need a visa to visit any country in South America as a tourist. However, you should make sure that:
- Your passport must have 6 months’ validity remaining on the date of entry to each country.
- You should have at least one blank page for each country you will visit.
