Can I apply for a visiting visa for my 16 years daughter who is just schooling? What would be the process?

Visitors visas are issued only if the U.S. Consulate officer is convinced there is a strong liklihood that she will return to her home country when the visit is completed. If she doesn't have a job or her parents don't put up a deed of trust on their home, then it will be difficult. Additionally, a visitor visa doesn't allow the beneficiary of that visa to study or to work, only to visit.
