Yes. You need to always be honest on all of your immigration applications regarding all: Arrests (including those by police, Immigration Officers, and other Federal Agents); Convictions (even if they have been expunged); and Crimes you have committed for which you were not arrested or convicted. Even if you have committed a minor crime, Immigration may deny your application if you do not tell the Immigration officer about the incident. It is extremely important that you tell Immigration about any arrest even if someone else has advised you that you are not required to do so.
