GC holder(through employment) marry US citizen

[Krishna04]

I had my GC 3 years back through employment based process. My husband is a US citizen (married 6 months back). When can I apply for my US citizenship?

You qualify for naturalization under the 5-year rule if you've had a GC for 5 years. You qualify for naturalization under the 3-year rule if you've had a GC for 3 years, and you have been married to a US citizen for 3 years (i.e. you have been married to the same person for 3 years, and that person has been a US citizen for 3 years), which for you will be 2.5 years from now, which is later than when you would qualify under the 5-year rule.
