For a US citizen a criminal conviction can result in his or her doing jail, paying fines, and/or having to enter into treatment if the court believes it is appropriate. However, individuals that are not citizens face an aditional very serious challenge. Legal Permanent Residents or undocumented individuals can be placed into deportation procedings as a result of a criminal conviction. Many crimes, even those misdemeanors that may seem minor, can have very severe immigration consequences and trigger deportation. If you are accused of a crime and you are not a citizen, you need to make sure that you inform your attorney of that fact so that he can address your case accordingly.
