I am in Canada, how can I apply for a tourist visa to the United States?

You can apply in Canada and go to the local American consulate or embassy.

The booking of tourist visas in the United States needs to start to 1 month 3 days in advance.

Materials required for the interview:

The materials required for a tourist visa in the United States are prepared according to the situation.

General preparation materials are as follows:

1. Passport.

1. Original passport valid for at least half a year when leaving the United States, leaving at least one blank page of the applicant's original passport;

2. A copy of the first page of the passport;

Please sign your name on the last page of your passport (Chinese name);

4. Holders of reissued passports should provide all original passports at the same time.

Second, photos.

51x 51mm 2 color bareheaded photos (with ears exposed on white background) within 6 months. If local shooting is unconditional, you can take photos at the photo studio near the embassy the day before the interview.

Third, business cards.

Two personal business cards.

Extended data:

A tourist visa can stay for up to 6 months at a time.

Travel, entertainment, visiting relatives and friends, medical treatment, attending conferences, going to exhibitions and handling personal affairs in the United States can all apply for a B-2 American tourist visa.

B-2 American tourist visas can be divided into three months, 1 year, three years, five years, 10 year and permanent, and the number of entry times can also be divided into single entry and multiple entry.

American embassies and consulates in different countries or regions, or different consuls in the same consulate, have great discretion over the validity or number of entry visas.

For example, it is easier for Hong Kong residents to apply for a B-2 visa valid for multiple entry for 1~5 years, while it is easier for China mainland residents to apply for a B-2 visa valid for one or multiple entry for three months to 1 year.
