You cannot bring your parents to live with you on your student visa. The F-2 dependent visa is only for your spouse and your unmarried children under 21. Parents do not qualify.
Your parents can still visit you. The usual route is the B-2 tourist visa. With it, they can come for a visit, but they cannot work, and they cannot enroll in a degree program. Short recreational courses are sometimes allowed, but anything leading to a degree is not.
At the border, an officer decides how long they may stay. B-2 visitors are often admitted for up to six months. If they need more time, they can apply to extend their stay with USCIS using Form I-539 before their authorized stay ends.
For the visa interview, your parents should show ties to their home country, such as a home, a job, or family, plus enough funds for the trip. A copy of your I-20 and a letter confirming your enrollment can help show the purpose of the visit.
Health insurance is worth arranging. Visitors are not eligible for public health programs, and American medical care is costly without coverage.
