kastamandap, it is always a good idea to go for 485 once you received your 140 approval rather than going for cuncurrent filing, it expedites your process significantly. now, you said your 140 is already approved, you will receive your GC approval within 45 days if everything goes ok, but if you are RFEd, and /or found anything wrong on your security, fingerprint check....then not before 6 months at least.
