Singapore offers permanent residence through the Professional/Technical Personnel and Skilled Workers (PTS) scheme. Applicants must be highly skilled workers between ages 21-60, hold an employment pass, have lived and worked in Singapore for at least 2 years, and can demonstrate how they will contribute to the economy. If approved, applicants can gain permanent resident status for themselves and their families. The PTS scheme is the most common path to permanent residence in Singapore due to the country's strong economy and business environment.
