Depending on the exact circumstances surrounding your father's removal from the United States, he may be able to re-enter the country after ten (10) years. Assuming you are over the age of twenty-one (21) you, a U.S. citizen child, are eligible to sponsor your father for a green card. That said, additional facts are needed to give an accurate response to your question. Contact an immigration attorney with questions regarding your case.
