Which country sends the most visitors to the U.S.?

Canada sends the most visitors to the U.S. due to several factors including geographical proximity, cultural similarities, and strong economic ties. The close border allows for easy travel, with many Canadians visiting the U.S. for leisure, shopping, and various services. Additionally, Canadians do not require a visa for short visits, which encourages more frequent trips. This high volume of travel is also supported by well-established transportation links such as roads and flights between the two countries.

While other countries like China, Germany, and Brazil also contribute significant numbers of tourists to the U.S., the sheer volume of Canadian visitors consistently outpaces those from other nations, making Canada the leading source of international visitors to the United States.
