Thanks VulcanI and depends. I have also read on some of the forums that one has to be married for a year or two to apply for a PR. Would applying immediately (within 4 months) be viewed negatively? I don't know how much of my education (dual degree) and work experience will be looked into while evaluating my application. If it is then I presume it will help atleast make my appn stand out in terms of other factors (possibility of finding a job, contributions to CPF etc).
I'm not sure what their criteria is based on, but I'm single and applied within a month after arriving here on an EP. Got approval within a couple of months.
