If you missed the NS Registration deadline/period, a Further Reporting Order (FRO) will be sent to you within 7 working days after the closing date. You will need to report to the Central Manpower Base (CMPB) on the date and time indicated on the FRO. On that day, you will be required to attend the pre-enlistment medical screening. It is important not to visit CMPB on a date or time other than what is stipulated on the FRO, as the pre-enlistment medical screening is by appointment only.
