Now, retrenchment and salary cut happen everywhere in Singapore. I personally won't suggest you coming to Singapore.
If you really insist, I would suggest you making a detailed plan including budget, which should include the following:-
1. What kind of job are you looking for?
2. What kind of skill do you possess to ensure that you can still get that job, among all competitors in Singapore?
3. How long do you expect to get the job?
4. How much do you need to have to sustain your life here before you get your first salary?
5. What kind of VISA/PASS do you need if you want to look for a job in Sinagpore? Definitely not normal visitor pass. Legally, vistor pass holders are not allowed to look for a job in Singapore. You would require EP certificate.
Other than the above, you will confront more questions.
