I heard that architects settle late.is that true???

What exactly you mean here by settling late? If you mean settling into the job / career late then probably it is true because an Architect has to make a name for himself/herself and that takes some time.

@ mathur has said Wright this is the harsh reality in Designing Field. Architect has limited Scope in India as compared to other Countries. Even India's Top College for B.Arch that is SPA Delhi Doesn't have a Placement Cell.
