Yes, lying on a past visa application is considered misrepresentation or fraud, which can make you inadmissible to the U.S.

Common lies that cause problems include fake job offers, false travel purposes, hiding prior immigration history, or fake documents.

To qualify for a waiver, you usually must show that denial would cause extreme hardship to a U.S. citizen or green card holder spouse or parent.

If you admit the truth voluntarily and explain the circumstances with legal help, that may help reduce the damage.
