I have made some research on previous posts but wasn't able to find the answers I need. I have also look on the immigration website but I'm still not sure of the answer.
So, I'm keeping it short


Can someone confirm this please ? Also in order to apply for a long term visitor pass it seems required to have a local sponsor (PR or Singaporian) what happend if we don't know a local sponsor ? Are we still able to apply for a long term visa ?
Also is it possible to go out of Singapore and come back during the three months periods? (Can I go to Hong-Kong for the weekend and come back to Singapore without immigration problem?).
Sorry if those questions have been already asked (and answered), feel free to redirect me to the appropriate topics.
Thanks in advance for your help !!!
