I know, it does sound funny. Why would anyone needs to be invited just to travel to Singapore or to a certain country?
For some countries with tightened migration policies, the Immigration Officers (IO) of that country might be asking for an Invitation Letter (IL). Usually, they would want this to be authenticated by the Embassy.
After checking-in your luggage, you will pass through the IO. Aside from doing the routine passport scans and documentation checks, they would sometimes ask you about your purpose in going to such country. If you don't have any relatives in the country, they may ask for a confirmed hotel booking. If you happen to have a relative there, they may ask you for an IL.
