1. There are differences in tax obligations. U.S. Green Card holders have to pay taxes to the United States no matter where they are. Canadian Maple Leaf Card holders do not need to pay Canadian taxes if they do not live in Canada.

The residence requirement for U.S. green card holders is that they must live for half a year within a year. Otherwise, they may be subject to detailed inspection at the customs and may even lose their immigration status. For Canadian Maple Leaf Card holders, the residence requirement is that they can maintain their immigration status by living for two years within five years. This means that they do not need to live in Canada for the first three years.

3. There are differences in the convenience of international travel. Green card holders from the United States and Canada enjoy visa convenience when entering certain countries. For example, they can enter Mexico, Switzerland, Dominica, Jamaica and some Caribbean island countries without a visa, and transit in South Korea without a visa. However, American green card holders do not need a visa to enter Canada, but Canadian Maple Leaf card holders do need a visa to enter the United States. Even so, Canadian Maple Leaf Card holders can generally easily obtain a multiple-entry visa to the United States, so traveling to the United States is relatively less inconvenient.
