I am married to US Permanent resident since 6 years. She had her green card 8 years back. Do i need 3 or 5 years to apply for citizenship.

Regardless of the time that you have been married to a permanent resident and the number of children that you have with her, the amount of time to apply for citizenship is five years unless your wife becomes a US citizen. Then you can count three years from that date and can file 90 days before the three years as long as you have both been living together without significant break during the three-year period.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.
