Unfortunately, there is a very little scope of Mechanical Engineering in Pakistan for girls; may be because of our male dominated society or perhaps girls don't opt for this choice or you can say they aren't permitted by their parents/guardians. However, if you are expert in this field and you can surpass your male workers in skills and work, you can be the first to open a new for girls in Pakistan. Any field you choose, doesn't matter but you must be expert in your field.
All the Best!
