For international students in the U.S., OPT (Optional Practical Training) is a common route to gain work experience. OPT allows students with an F-1 visa to work in the U.S. after finishing their studies. A question many students have is whether they can do unpaid internships during OPT.
The main goal of OPT is to help students gain practical experience related to their major. U.S. immigration rules specify that any work done during OPT must be paid. Unpaid internships don’t meet this requirement because they don’t guarantee meaningful work or follow OPT rules. If the internship doesn’t relate to the student’s field or doesn’t offer payment, it might not count as valid OPT work.
Some students might think about doing unpaid volunteer work or internships at non-profit organizations. While this is possible, the work must still relate to the student’s academic field and meet the specific rules for non-profits. A non-profit role can qualify for OPT, but it must have an educational purpose, not just free labor.

The core requirement for OPT is that the work must be paid and related to the student’s academic background. Most companies are familiar with these rules, so students should ensure their internships meet the guidelines and inform employers of their visa status. This helps avoid issues with internships that don’t follow OPT rules.
It’s better to choose paid internships that align with your field of study to gain valuable experience. In conclusion, unpaid internships during OPT might not meet immigration requirements, so it's safest to aim for paid opportunities that comply with the rules.
