I am currently P2 pass holder and living in Singapore for 3 years. After one year in SG, we (me+husband) applied for PR at Jan 2009. It was rejected and applied again in Nov 2009 (only for me). It was rejected again and I appealed in Aug 2010 after our baby girl was born here. It was rejected again

I really want to settle down in SG. I intend to apply PR again in August this year. Is it suitable time? or How long should we wait to apply again?
