how can I abtain a federal pardon in order to return to the u.s after being deported ?

For a person deported with an aggravated felony, return to the US is extremely difficult if not impossible. If you obtain a pardon, you may of course under a petition by your wife, but all politicians are very wary of using powers to pardon which could damage them politically. Generally pardon requests are made to the president or to state governors. Each state has its own procedures for dealing with individuals requesting pardons. The  ex-governor of New York, David Paterson, strongly believed in helping permanent residents who were at risk of deportation because of long-ago or minor convictions and pardoned a number of individuals for old crimes. The law provides that a full and unconditional pardon by the president, governor of the state, or constitutionally recognized executive body prevents deportation for crimes of moral turpitude, including aggravated felonies. A pardon request to the president can be made to the Office of the Pardon Attorney, 1425 New York Ave. NW., Suite 11000, Washington DC 20530.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
