Do you need a visa to travel to the United States (about a week) while studying in Canada?

Hello, if you study in Canada, you need to apply for an American visa. If you study in the United States, you also need to apply for British and Canadian visas. If you have studied in a country for more than half a year, you can apply for a visa from another country locally. As long as the materials are prepared according to the requirements of the embassy, you can almost succeed.
