how much would it cost to file I-212 form

Unfortunately, your question appears to be too vague to answer and I would suggest that you or your father make a telephonic or other appointment with an immigration lawyer to go over his entire situation. You should keep these points in mind – a permanent resident is generally not removed without cause and so a question is whether the basis of the removal still serves as a bar today. Is he eligible for an I-601 waiver if the basis was crime or fraud/misrepresentation? Generally speaking, a person who has been removed is subject to a 10 year bar. If such is applicable in your father’s case, he would not need an I-212 waiver to return to the States (as long as he still has a basis to immigrate) since he has already been out 13 years. On the other hand, is your father under the permanent bar for having entered or tried to enter illegally the US on or after 4/1/97 after having been in the US illegally for one year previously or deported. If that is the case, your father would only be able to file the I-212 after 10 years. 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.
