transit visa

Indians (and lots of other nationalies) have to apply to the Singapore embassy for a transit visa. It allows you to remain in the airport before you catch a connecting flight to another country.  At every airport in the world, you have to go through immigration when you disembark a plane.

Ehh what? No.

If it's a transit flight then you don't necessarily go through immigration, in fact more likely that you do NOT go through immigration in the airport where you transit.

Of course there are some exceptions, for example if your transit also means change between different airlines, coming from outside schengen to schengen for transit to another schengen area, etc.

Please provide a source for your statement that "Indians (and lots of other nationalies) have to apply to the Singapore embassy for a transit visa.".

It is when you travel through one country to get to another, you are simply passing through a country so don't require a full visa as you are not staying there for any length of time. So just a transit visa is required, which is usually cheaper and only valid for a short time.
