For immigration applicants, one of the most concerning issues after successful immigration is the "immigration monitoring" requirement. It is referred to as "immigration monitoring" because many applicants must remain in the country they are immigrating to, similar to being in prison (short-term departures are allowed), as leaving for an extended period may prevent them from applying for citizenship or may result in the loss of their immigration status. Generally, the conditions for "immigration monitoring" for permanent residents are relatively lenient, but the requirements become much stricter when applying for citizenship.
United States: Entering the country once every six months is sufficient to retain the green card
After obtaining a green card in the United States, applicants only need to enter the country once every six months to retain their green card, which is a relatively easy requirement for domestic applicants to meet. To apply for citizenship, however, they must reside in the U.S. for at least two and a half years within a five-year period. According to immigration law, the time a green card holder spends in the U.S. before applying for citizenship must include at least two and a half years of residence within the five years prior to the application, with at least six months spent in the U.S. each year. If they leave the U.S. for more than six months in any given year, the remaining months cannot be counted towards the two and a half years of residence, and if they leave the U.S. for more than one year, the calculation of residence time will be interrupted.
Singapore: No immigration monitoring requirements
In terms of procedures, Singapore's investment immigration is relatively simpler compared to countries like the United States and Canada. As long as the necessary documents are prepared and submitted for review by the Singapore Immigration and Checkpoints Authority, those whose documents are approved will be invited for an interview in Singapore. Additionally, Singapore has no immigration monitoring requirements; after successful immigration, the residency requirements are very lenient, with no need to meet a specified number of years of residence, which is a significant reason why many Chinese investors choose the high-cost investment immigration to Singapore.
