Hi,
I have travelled to USA via chennai-singapore-tokyo-US. The transit time is less and there is no issues when going to USA. But while returning USA-TOkyo-Singapore-chennai, i have a bad experience in Singapore Airport. I have reached singapore airport by 10 or 12 pm and i have to stay inside singapore airport to catch next flight by morning 8am. As it is a transit and i have no visa to go out, i stayed in airport. I slept in sofa and group of 5 police men during their regular rounds come and surrounded me. They ask for my passport and i gave. I photo looks little bit difference from what am i, my face got changed after my marriage. But i have told about my identity in my face like scar and mole to compare. They treated me rudely and ask me shut my mouth. I even told that i have my photos in ipod to show. They not even listen. I took me to the immigration room to take photo and that computer is not allow them to login, they didn't take a snap. If i speak, they said shut my mouth again but very harshly. Then a lady who is also a police ask me whether i'm coming from USA and my destination is chennai and ask i'm on transit in singapore. She ask all my boarding pass and i showed it, i told that i have to collect my boarding pass by morning 7am at airlines counter to catch my 8am flight. Then they spoke something in Malay and allow me to leave. Then i go and sleep at the same sofa at the same place.

This is very my very bad experience in my life. Where people not ready to listen and treated me harshly. I have no such incidence in USA or Tokyo. They also checking my identity and they are also strict in what they suppose to do. But they always smile and give a comfort.

In singapore they validate my passport and USA visa several times when i try to get my boarding pass.

I came to know the same happened to some of my friend also.
