Why did my non-immigrant US visa get revoked?

Under the established regulations for visa revocations, the Department of State and consular officers abroad operate under slightly different visa revocation parameters. Visa revocations can happen for a variety of reasons and the impact of a visa revocation can vary from case to case depending on how that revocation was undertaken. Although only the Department of State or a consular officer can undertake a revocation, Department of Homeland Security officials are empowered to cancel visas if warranted.
