My first cousin and his wife did their MBBS from PIMS Islamabad (they met there and got married after graduation).
Both migrated to US and live in California. The cousin works in the ER department of a big hospital, while the wife is a general practitioner. They have a HUGE mansion, and I mean HUGE. They have three Teslas. I don't know about the wife, but the husband earns upwards of $300/hr and is one of the most senior (and respected) doctors in his hospital. Alhumdulilah.
The down side is the husband has crazy shifts and works 22 days on and 3 days off. Even in days off he is sometimes on call if a special case arises. Besides working in an ER department you are faced with the most gruesome and worst cases on a daily bases.
One thing I love about the US is they value talent, expertise and hardwork. If my cousin had stayed in Pak he would have been toiling away with no hope of progression or earning nearly as much as he deserves.
