Canadian immigrants can hold a maple leaf card, which is valid for five years according to the Canadian government regulations. Before the five-year period expires, if an immigrant wants to maintain his identity, he must live in Canada for 730 days, which is equivalent to two consecutive years. During the two years, immigrants did not need to keep in touch with their place of residence frequently, a regulation commonly known as Canadian immigration prison. If the permanent resident is appointed by a Canadian business or institution to work in another country, it is equivalent to living in Canada; at the same time, his spouse and children accompanying him are also deemed to be living in Canada.

In addition, if the permanent resident is abroad with his spouse and his spouse has obtained Canadian nationality, his behavior is equivalent to living in Canada. Therefore, the Canadian immigration surveillance regulations do not mandate individuals to be in Canada, as long as they pay taxes in Canada. Regarding naturalization, Canada stipulates that permanent residents must live in Canada for a total of three years within the five years before applying for citizenship. It should be noted that the residence time of these three years must be in Canada. If you have been in Canada for the first three years, you can apply for naturalization in 3 years

US immigration prison

After obtaining the US residence permit (green card), log in to the US every 180 days.

If the spouse holds US nationality and obtains permanent residence, and lives in the United States for 18 months (i.e. one and a half years), he can apply for naturalization within three years.

Others need to live in the United States for 30 months within 5 years before applying for naturalization.
