Can American passports be exempted from visas in Canada? Similarly, can Canadian passports be exempted from visas in the United States?

Passports of the United States and Canada are visa-free, which is similar to that of their own citizens. For example, you can take the other party's own citizen channel without making an online appointment (the United States and Canada require all visa-free countries to make an online appointment before they can enter the country visa-free). Moreover, this kind of visa-free is not only for tourism and business, but also for everything except immigration and work, including reading (the entry purpose of other visa-free countries must be limited to tourism and business, and others must be signed in advance, including reading, training, medical care and having children. All work visas in the United States require applicants to apply abroad, and each country has different quotas, but Canadian citizens do not have quotas and do not need to apply for visas on arrival in advance. In addition, the United States stipulates that if a Canadian citizen applies for a visa on arrival, it will not affect his entry. In other words, in theory, the American immigration officer at this window refuses to sign your work visa, so you can try it at another window immediately. Generally speaking, the longest stay period for both sides to enter the other country is just to avoid immigration. However, it should be reminded that the words used by American immigrants are based on the place of birth. If China people immigrate to Canada and immigrate to the United States with Canadian passports, they will still be regarded as China people, not Canadians. In addition, the land border between the United States and Canada was originally open. Before 9 1 1, as long as you hold each other's driver's license, you can enter the country smoothly. After 2007, it is stipulated that you must have a passport or NEXLUS to cross the border, but children under 16 can enter and leave each other with their birth certificates without any stay restrictions. A wonderful thing recently is that a Canadian citizen took a photo on the IPAD according to the passport photo page, and successfully entered the United States with only one photo without a passport. By the way, all the streets in Pennsylvania, the capital of the United States, are American government departments. The only exception is that the Canadian embassy is located with the US government department.
