If my consultant filed wrong information without my knowledge, can I still be found to have misrepresented?

Unfortunately, yes, in many cases. Misrepresentation under immigration law generally focuses on whether a material misrepresentation was made on the application, not solely on whether the applicant personally knew about or intended it — an applicant can be held responsible for information a representative submitted on their behalf, even if the applicant genuinely didn't know it was wrong.

There is a narrow exception for situations where the applicant honestly and reasonably had no way of knowing about the misrepresentation and couldn't reasonably have caught it, but this exception is applied narrowly and is not something to count on. Simply trusting a representative to handle the paperwork is generally not enough on its own to establish that exception, particularly if the applicant signed the application or otherwise had an opportunity to review it.

This is one of the strongest reasons to work only with someone properly authorized to represent people in immigration matters — a lawyer, a licensed paralegal, or a College-licensed immigration consultant — and to actually review what's being submitted before it goes in, rather than treating a representative as a black box. Anyone who discovers wrong information was filed on their behalf should get advice immediately rather than waiting to see whether it's noticed.
