The first step is to become a lawful permanent resident. Assuming the spouse is a United State citizen, the process will take approximately 6 to 8 months from filing of marriage-based adjustment of status package to approval. If the spouse is a lawful permanent resident, the process will be approximately two years due to visa availability during which time the alien will either need to maintain valid nonimmigrant status or depart the country. The earliest a lawful permanent resident could seek naturalization is three years after being granted residence. This assumes the spouses are still happily married.
