Foreign students studying in the U.S. on an F1 visa who are enrolled in graduate or undergraduate programs can take up a practical training job known as OPT (Optional Practical training).
OPT students can work without a H1B visa for up to 12-29 months, depending on their field of study. Students on an M-1 visa may also take up OPT for a maximum period of six months. They are allowed for one month training with four months of study. This type of insurance provides coverage for international students on OPT.
