(Fatwa: 802/H-122/TH=05/1435)
If Pune is your place of service and you have not adopted it as your permanent residence (watan asli) just you visit it for two-four or five days in a month then you will do qasr in Pune. And if you have to come in Nashik for two or four or five days then you shall offer complete salah in Nashik. The ruling pertaining to the native place (watan asli) is that if one visits it though for awhile he will not remain musafir. If you visit Pune and intend to stay there for fifteen days or more then you shall offer full salah in Pune.
Allah knows Best!
