I am a Singapore PR. Can I apply for an LTVP for my parents, who currently live in India?

If you are a Singapore PR and over 21 years old, you can sponsor Long Term Visit Passes for your parents. You can apply online using e-services. The duration and validity of LTVP for your parents will be tied with your Singapore PR validity dates. So if your PR REP remaining period is 2 years then the LTVP for your parents will be approved for two years.
