Unless you are a Citizen your child will be a stateless person until you register the birth with the Phillipine Embassy. Children of PR's unless one parent is a Singapore Citizen cannot obtain SG citizenship at birth. Depending on your visa status in Singapore, you may be given a Dependents Pass for the child but possibly for only 1 year after than it's anybody's guess. They might require the child to be repatriated to the Philippines.
What is your visa status in Singapore?
SOME PEOPLE TRY TO TURN BACK THEIR ODOMETERS. NOT ME. I WANT PEOPLE TO KNOW WHY I LOOK THIS WAY. I'VE TRAVELED A LONG WAY, AND SOME OF THE ROADS WEREN'T PAVED. ~ Will Rogers
