then I came back to my country.
I am trying to find a job in sg but seems quite hard

One of my friend is doing her own shop and asked me to work together like business partner.
But she can only give me WP as it’s service sector ...
My long term plan is to apply PR and stay long in sg..
I’m afraid if I get WP then it will be hard to get EP or SP again when I want to get back to my previous work...
Anybody had this experience before like EP/SP to WP or WP to EP/SP??
