After a master’s degree, you can usually stay and work in the USA for up to 12 months through Optional Practical Training (OPT). The work must relate to your field of study.
If your degree is in a qualifying STEM field, you may be able to extend OPT by 24 months. That gives STEM graduates up to three years of work authorization after graduation.
To stay longer, you need a work visa, usually the H-1B. This requires an employer willing to sponsor you. H-1B visas are issued through an annual selection process, and far more people apply than there are places. Selection is never guaranteed.
Your employer starts the H-1B process, not you. Talk to your employer’s immigration team early, ideally during your OPT period, so deadlines are not missed.
After several years on a work visa, an employer can sponsor you for a green card. That process takes more time and depends on your category and country of birth.
Keep your status legal at every step. A gap in valid status can end your stay. Your school’s international student office and an immigration lawyer can help you plan the timeline.
