I am a Singapore PR since 2013.
Before that, I was studying in Singapore (2005-2011, BEng/MEng). I started working as an engineer in 2011. I left Singapore in 2015 and my re-entry permit will be expiring in March 2018. Since I don't have a job in Singapore my chances of renewing the re-entry permit are extremely low, perhaps nil.
Is there is a chance I can get the permit renewed if I Volunteer to contribute to the CPF? If so, what are my chances?
If my re-entry permit renewal gets rejected, is it mandatory to renounce my PR?
Can I not renounce my PR, and in a few years' time can I come to Singapore, find a new job, and start working? Should I first get an EP pass and go through the process from beginning or I simply apply for a new re-entry permit?
