Depends on the country you are going you might not need an
international license at all.
International license is just a translation of your current
license.. nothing else. Some lousy looking booklet that some
countries don't recognise it as valid ID.
You can get it at Automobile Association for $60 i think valid for
1 year only.
Go www.aas.com.sg for more info. You need 2 photos.
which countries are you going?
IF you are going USA & Canada, Intl license will help by
extending your allowable limit to drive with a foreign license to
up to 6 months to a year depending on the jurisdiction.
