Many H-1B visa holders have received emails from US consulates saying their visas were "prudentially revoked". This revocation starts immediately unless the visa holder is inside the US, where it only takes effect once they leave. US immigration attorney Emily Neumann explained, "Many of these incidents were already disclosed and cleared in earlier visa stamps. A revocation does not affect lawful stay in the United States, but it means the issue will be reexamined at the next visa appointment." She noted this seems inefficient since the cases were already vetted. So, what does prudential revocation mean? It is a temporary, caution-based cancellation of the visa stamp. If a visa holder is inside the US when their visa is revoked this way, they can stay legally until their current visa expires. However, the revoked visa stamp in their passport is invalid. If they leave the US after such revocation, they may not re-enter without a new visa. Many visa holders worried on Reddit if their US stay became illegal or if they were at risk of arrest. Lawyers say the revocation cancels only the visa stamp and not the person's legal status inside the country. Can holders fight these revocations? Usually, there is no appeal. People must reapply for visas. While no ban exists on reapplying, officials will closely check why the visa was revoked before. For those with DUI cases, they need to show proof the case was resolved to improve chances. This move follows a broader immigration policy update from the US government, affecting many visa holders across the country.
