What are the stay-back and work opportunities in the USA for STEM-designated programs compared to non-STEM programs?

In the USA, international students generally receive 12 months of OPT (Optional Practical Training) after graduation, which allows them to work in roles related to their field of study. Students graduating from STEM-designated programs (Science, Technology, Engineering, Mathematics) can additionally apply for a 24-month STEM OPT extension, giving them a total of up to 3 years of work authorization in the USA. This longer duration is a major advantage because it provides more time to gain work experience and attempt H1B visa sponsorship. However, to receive the STEM OPT extension: • You must have a relevant job at the end of your initial 12-month OPT period, and • Your employer must be registered with the E-Verify system, which is a US government employment verification program. Non-STEM program graduates receive only the standard 12-month OPT period, after which students typically need another visa, such as the H1B visa, to continue working in the USA. Because of the longer work authorization period, STEM-designated programs are often considered more favorable for international students planning long-term careers in the USA.
