1. At JFK, do I need to inform SQ during check-in that I plan to enter Singapore? Not sure if they would check for any documents.
2. I assume they will give me the boarding pass for the SIN-MAA leg at JFK. My flight to MAA departs at 2015 on a Thursday. When should I arrive at Changi T3 to clear Immigration, Customs and Security? I happen to be a US citizen.

Thanks!
