Yes, it is one of the advantages of becoming a PR: a Singapore PR may apply for Long Term Visit Pass (LTVP) for his/her first degree family members i.e. Spouse, children (below the age of 21 years old) and parents. This will allow the family member(s) to stay long term in Singapore (minimum up to 1 year). However, the LTVP holder will not be allowed to work under this pass. The LTVP will be under the Immigration and Checkpoints Authority’s (ICA) purview instead of under Ministry of Manpower (MOM), as in the case of Dependent Passes (DP) or LTVPs of a work pass holder (SPass / EP / PEP).
Another advantage of being a Singapore PR is the chance to take up Singapore Citizenship. This is the ultimate goal of those who are serious about living and working in Singapore long-term. For more information, you may refer to Singapore PR page.
