Are you expecting a newborn son? Don't be surprised if you receive a letter from Mindef. Facebook user Iskandar Shah published the photo shown above on 21 July 2018 and has since gathered over 700 shares. Implemented in 2017, Mindef has been sending out letters reminding parents of their newborn son's obligations when they hit the age of 18. The letter touches on "NS policies, such as applying for exit permits and deferment for full-time studies. It also states that the Government may withhold an individual's renunciation of citizenship if his NS liabilities are not fulfilled."
