I'm preparing the documents required for apply PR. From the Explanatory notes, I noticed that one of the documents to be produced is the "Testimonials from previous employer stating the nature and duration of employment and also the last drawn basic salary". Anyone know that is it compulsory to submit this testimonials? This is because my previous employer migrated to oversea... currently I can't contact him...
Besides, I also have some other questions:
- Is it need to submit the testimonials from my current employer?
- I need to submit the payslips for the last 6 months, can I know that the copy of payslips need to be signed by my current employer as an approval ?
- My employment pass will be expired in March 2015. I need to give a copy of my pass. So, when processing my PR application, I will renew my pass.. I'm thinking whether I need to give the copy of pass again after renew my pass? Any impact on applying PR if the EP pass near expiry date...
Any suggestions and comments are welcome and appreciated.

Thanks.
