if ur stay is less than 12mths in singapore. u r not required to
convert ur license. u still can drive in singapore with ur valid
Dubai driving licence with proper english translation. but after
12mth stay, u must compulsory convert.
this is e proof
" If you are a foreigner and hold a foreign driving licence and
intend to remain in Singapore for less than twelve months, you are
not required to convert your foreign driving licence to a Singapore
driving licence. You may drive in Singapore with a valid foreign
driving licence. However, if your licence is not in English, in
addition to a valid foreign driving licence, you are required to
have an International Driving Permit. If an International Driving
Permit is not available, an official translation of your driving
licence in English is required.
If you are holding an Employment Pass/Dependent Pass/Student
Pass/or Work Permit and are likely to reside in Singapore for more
than twelve months and you wish to continue to drive in Singapore,
then you are required to convert your foreign diving licence to a
Singapore driving licence before the end of your twelve months
stay. "
