I plan to enter KLIA via Singapore (Manila – Singapore – KL; transiting via Singapore) and also depart KLIA via Singapore (KLIA – Singapore – Mumbai) within 2 days. Entire ticket on a single PNR and I am an Indian citizen. Since I am entering KLIA via Singapore only via transiting and not having actually got any Singapore immigration stamp – is this OK ?
You will have to apply for an eVISA because the condition says you need to travel from/to India via Singapore, Brunei or Thailand. Since you are travelling from India to Philippines and then Singapore, you will not be eligible for eNTRI:
eNTRI Note (Tourism) :
(Terms and Conditions:
ENTRY:Travellers are permitted to travel from India to Malaysia. They are also allowed to travel from India via Singapore, Thailand or Brunei to Malaysia.
EXIT: Travellers only can exit Malaysia by a direct flight back to India. They are also allowed to exit via Singapore, Thailand or Brunei before arriving back to India.)
Hope it helps!
