Sealing your conviction will help with your job search. Therefore it might be a very good idea. However, it will remain as a conviction for immigration purposes and you will always be required to disclose it on immigration related documents. Therefore, you should always keep two certified copies of the relevant documents. Because a felony conviction is a serious matter, it could affect your ability to become a U.S. citizen. Furthermore, if it is considered an aggravated felony or domestic abuse, it might also serve as a reason to revoke your green card. Experienced immigration counsel is a must in this type of case.
