AKUH is a very reputable institue in the whole world. Most of the graduates from the university move abroad with no problems. They are in high demand. Working there will only enhance their CV. There are other things to consider but the credibility of AKUH isn’t n issue.
I had friends who spoke a different language and could communicate with others(pak has many regional languages). English is spoken widely in pak and initially it may be a struggle but u can learn rudimentary Urdu to communicate. It’s easy to pick a language when u live in the country.
OP think it from your own point of view and consider of all the pros and cons.
