You certainly can pursue MA psychology while you are working, but that would be from universities like Annamalai or IGNOU and similar others. Even while you do these you will have to go these colleges for the practical bit, as for that you have to be present personally.
Nevertheless, if you are looking at MA psychology as an added thing to your qualifications then this will help.
But you can get in to proper counseling since your degree is going to a correspondence one.
Hope this helps.
