Because Pakistan is not a treaty country for the E-2 visa, that investor category would not be directly available to you. However, you might explore forming a U.S. company and seeking sponsorship under another employment-based category if the business grows.

Another possibility is coming to the U.S. on an F-1 student visa and later using Optional Practical Training (OPT) to work on your startup if it relates to your field of study. This route allows you to build experience while maintaining legal status.

If your business idea is highly innovative and has strong growth potential, you may eventually qualify for the International Entrepreneur Parole program, which allows certain startup founders to stay temporarily in the U.S. without a traditional visa. This requires demonstrating significant investment from qualified U.S. investors or government grants. You could also consider partnering with a U.S. citizen or permanent resident who can play a principal role in the company. Carefully reviewing eligibility requirements and long-term strategy is essential before making plans.
