Is Singapore PR lifelong or is it valid only till certain period?
A Permanent Resident status is permanent. But: you do need to renew your re-entry pass. When you have PR status, it has no expiry date, but your re-entry pass does. You need to renew that pass, often every five years, but other renewal periods exist.If a PR resides outside Singapore for some time, and tries to renew the re-entry pass, the renewal may or may not be accepted. There are no clear published rules, and it seems to depend on a set of factors (having ties to Singapore, income and education, how long you were away, your stated reason for being away). I have friends who became PR after living and studying in Singapore for years, then going to work overseas. When it was time to renew, they got a one year re-entry pass duration, which could be upgraded to five years if they were back in Singapore when they next renewed. In the case of these friends, they did not come back, and duly did not get their renewal.
How long after someone is fired can they be rehired at the same place?
That depends on the company and the reason for being fired. Companies may have explicit policies for re-hiring terminated employees or it may be a subjective process. Either way there’s no guarantee that an employer will take an employee back after any amount of time has passed.If the reason for termination was due to downsizing or layoff then a former employee might have a decent chance of getting rehired when the company is in better financial shape. However, the timeline for that is unpredictable. In fact the company may never get back on its feet.If the employee was fired for performance reasons then I’d expect the employee would have to demonstrate how they’ve changed since being terminated. Was there some personal situation that has since been remedied? Has the employee received additional training or education? Have they demonstrated a strong record of employment at another company? A company is less likely to rehire a poor performer than someone they had to let go because of downsizing. Still, if the employee has demonstrated some form of progress they might take them back. How long it would take to get rehired would depend largely on how long it takes the employee to demonstrate a significant change in circumstances.If the termination occurred due to criminal activity, an ethical lapse or because of intentional actions that brought serious harm to the company then the most likely answer is “never.”
