Hello,

After completion of your architecture course, one can practise on his/her own after getting registered with the COA, which grants license for practise.

You can also start working with an architectural firm or under the guidance of well established architect.

Real estates firms employ architects and also Delhi metro Rail Corporation employ architects.
