📋 Summary (TL;DR)
- It is legally permissible to file for a Change of Status (COS) via USCIS while physically present in the United States.
- The USCIS 90-Day Rule presumes willful misrepresentation if a change of status or employment is pursued within the first 90 days of arrival.
- A B1/B2 tourist visa strictly prohibits unauthorized employment; working without an EAD triggers deportation and 10-year entry bans.
- You must maintain lawful nonimmigrant status until USCIS approves your petition.
Understanding the Difference: Visa vs. Status
A Visa is an entry document stamped into your passport by a US consulate abroad, allowing you to travel to a port of entry. Status (Form I-94) is granted by CBP upon entry and governs how long and under what conditions you may lawfully stay within the US.

The Critical 90-Day Misrepresentation Rule
When entering on a B1/B2 visa, you attest that your primary purpose is temporary tourism or business meetings. Under Department of State and USCIS guidelines, taking actions inconsistent with visitor status within 90 days of entry—such as enrolling in school, seeking employment, or filing for permanent residency—creates a legal presumption that you misrepresented your original intentions.
To mitigate this risk, any legitimate shift in plans must be filed after the 90-day threshold, supported by comprehensive evidence proving the change was spontaneous and unplanned.
Transitioning from B1/B2 to F-1 Student Status (Form I-539)
- Obtain an official Form I-20 from an SEVP-certified institution.
- Pay the mandatory SEVIS I-901 fee ($350).
- Submit Form I-539 (Application to Extend/Change Nonimmigrant Status) with USCIS before your I-94 expires.
- Provide proof of financial solvency covering tuition and living expenses.
- Do not begin classes until formal written approval is granted by USCIS.
