Hello aspirant

Yes, definitely it is available. If you are applying for PhD in a college, try and ask them if they have any position of Asst Professor vacant, because in that way you can work in the institute as an asst prof and also do your PhD.  Although try to finish your PhD as soon as possible beacuse it so happpens in part-time PhDs that people take their Day jobs more seriously than their PhD and drag it for 8-9 years and in doing so, they sometimes loose interest in their PhDs.
