Quick answer: An NS exit permit in Singapore lets NS-liable males stay overseas for a long time. Boys who are Singapore Citizens or PRs need one from age 13 for stays of 3 months or longer. NSmen need one to stay overseas for 12 months or longer. You apply on OneNS, and some cases also need a bond.
The exit permit rules come from the Enlistment Act 1970. This guide explains who needs one and how to apply. It also covers bonds, PR sons and the papers to prepare.
An exit permit is official permission to stay outside Singapore for a long time. It applies to males who must serve National Service (NS). NS is the duty to train and serve in the army, police or civil defence.
The Central Manpower Base (CMPB) runs NS enlistment and the exit permit system. You do not need a permit for short trips. The rules depend on your age and how long you stay away.
All male Citizens and PRs aged 13 and above must follow these rules. When a boy turns 13, CMPB sends a letter about them.
| Who | Time overseas | What you need |
|---|---|---|
| Boys aged 13 to 16.5 | Less than 3 months | Nothing |
| Boys aged 13 to 16.5 | 3 months to less than 2 years | Exit permit |
| Boys aged 13 to 16.5 | 2 years or longer | Exit permit and a bond |
| Pre-enlistees from 16.5 | 3 months or longer | Exit permit and a bond |
| Full-time NSFs | 3 months or longer | Exit permit |
| NSmen | 12 months or longer | Exit permit |
A pre-enlistee is a young man who has not started NS yet. An NSF is a full-time national serviceman. An NSman has finished full-time NS and now does reservist duty.
PR families who move abroad have a second permit to think about. The parents and son also need a valid Re-Entry Permit for PRs living overseas to keep their PR status.
OneNS is the official NS website. You use it to apply, renew, extend, cancel or check an exit permit.
For overseas study, one exit permit can cover the whole course. So you do not need to apply every year.
CMPB does not publish a fixed processing time. Cases with a bond take longer, because the bank must issue the guarantee first. Apply well before the trip, and before the 3-month mark if you are already away.
Yes. OneNS is online, so you can log in with Singpass from anywhere. Keep your Singpass app working while abroad.
A bond is a promise of money. It makes sure the boy comes back for NS. If he does not, the government can take the money.
Some boys aged 13 to 16.5 stay away for 2 years or longer. For them, the bond is S$75,000, or half of both parents’ total yearly gross income for the past year. The higher of the two applies.
Boys from 16.5 also need a bond to stay abroad for 3 months or longer. CMPB tells you what is needed for your case.
Yes, if the rules are kept. CMPB releases the bond once the boy finishes or leaves his course and reports to CMPB before the permit ends. The bank and the parents are told when it is released.
Many parents we speak to are surprised by the bond size. Plan it with your bank early. Are any of your papers in another language? Then translators who help with CMPB papers can sort them out before you apply.
Male PRs must serve NS, just like citizens. This duty is part of the deal when a family takes up PR. If an NS-liable son applies to give up PR, ICA asks for a signed MINDEF acknowledgement form.
That form says giving up or losing PR without serving NS has serious effects:
Can a PR son give up PR before NS? ICA says the Government can reject or hold back a renunciation from a PR with NS duties still owed. In 2014, MINDEF told Parliament that no NS-liable PR who renounced in the decade before had been allowed to work or study here.
A son who simply does not register or enlist is an NS defaulter. That is an offence under the Enlistment Act. For more on how PR and citizen duties compare, see Singapore PR vs citizenship differences.
A deferment pushes back your NS start date so you can finish school. You can ask for it when you register for NS at 16.5 on OneNS.
CMPB may defer full-time study overseas up to A Level, a diploma, or the same level. Examples are the GCE A Level, the International Baccalaureate (IB), and polytechnic or ITE courses.
There are age limits. You must be younger than 19 (from Secondary 4) or 20 (from Secondary 5 or ITE). This is counted on 1 January of the year your course starts.
Deferment is never given for a university degree, even if you have already started one. You also cannot defer for a level you already hold, or a lower one. Has your son just come back from school abroad? CMPB asks such students to send papers on their overseas schooling, so translating foreign school certificates early helps.
Prepare these papers before you open OneNS.
Some parents work abroad and are paid in another currency. Their job proof may then be in a foreign language. In that case, think about translating a parent’s foreign payslip along with the employment letter.
For an overseas study deferment, CMPB needs a school letter. It must show the enrolment, the course, and the start and end dates.
Many overseas schools write these letters in their own language. CMPB’s pages do not set a translation format. So it is wise to send an English version along with the original.
Here are a few tips:
A letter from a school in Shanghai or Taipei is a common example. With Chinese school letter translation, each date and course name stays clear.
Plans change. Here is what to do.
Watch out for one rule. A boy without a bond may need one to extend. This applies if he has not come back before the permit ends, or has stayed away for 2 years or more in a row.
What if the school, course or departure date changes? For boys aged 13 to 16.5 staying under 2 years, apply for a new permit on OneNS. For longer stays, contact CMPB with supporting papers. For those above 16.5, CMPB checks the deferment again.
An extension is decided case by case. If the reason is an illness abroad, a foreign doctor’s letter in English helps CMPB understand it.
Breaking the rules is an offence under the Enlistment Act 1970. CMPB lists these penalties:
| Age | Possible penalty |
|---|---|
| 13 to 16.5 | Fine up to S$2,000. Each parent or guardian can also be fined up to S$2,000. |
| Above 16.5 | Fine up to S$10,000, jail up to 3 years, or both |
If the boy does not return before the permit ends, the bond may also be taken.
A common problem we see is families who think a short course does not count. Here are other mistakes:
Not for a normal holiday. Boys aged 13 and above only need one for trips of 3 months or longer. NSmen only need one for 12 months or longer. A long gap-year trip can cross that line, so count every day away.
Yes. Boys with dual citizenship are still liable for NS. Singapore does not recognise dual citizenship. If you keep Singapore citizenship at 21, you must give up your foreign citizenship.
Yes, for further medical reviews. He can see a doctor overseas at his own cost and send the report to the Medical Classification Centre. The overseas costs are not covered.
Some can. This is called disruption. It is open to NSFs who enlisted in a later intake than their school group. You need an unconditional university offer, and you apply on OneNS three months before the disruption date.
You can call the NS Contact Centre at 1800 367 6767 in Singapore. From overseas, call +65 6567 6767. You can also email contact@ns.gov.sg.
An NS exit permit lets NS-liable males stay abroad without breaking the law. Boys aged 13 and above need one for stays of 3 months or longer. NSmen need one for 12 months or longer. PR sons have the same duty, and skipping NS can hurt the whole family’s future plans.
Apply on OneNS before you leave, and plan any bond early. Keep the school letter, report cards and parents’ papers ready, with English versions where needed.
