I am a Taiwanese citizen seeking a green card through marriage.
We haven't get married yet, my girlfriend is a US citizen. We haven't filed any forms yet.
Attorney Answer
Congratulations on your engagement. Since you and your girlfriend haven't married yet and haven't filed anything with immigration, you're at the very beginning of this process, which gives you the chance to plan the smoothest path from the start.
Green card cases based on marriage to a U.S. citizen are governed by federal immigration law, the Immigration and Nationality Act, so the same basic rules apply whether you live in California or anywhere else in the country.
The general path looks like this:
1. Get married first. A valid marriage performed anywhere is the foundation of this process, and there's no waiting period required before you can file afterward. 2. File Form I-130. Your spouse, as the U.S. citizen, files this petition with U.S. Citizenship and Immigration Services to establish your relationship as husband and wife. 3. Choose the right next step based on where you are. If you're already living in the U.S. and entered legally, you may be able to file Form I-485 to adjust your status to permanent resident (8 U.S.C. section 1255, INA section 245), sometimes at the same time as the I-130. If you're outside the U.S., you would instead go through consular processing at a U.S. embassy or consulate. 4. Expect close review of the marriage itself. Because marriage-based green cards are common, officers look closely at whether a marriage is genuine. Keep evidence of your relationship, such as photos together, joint finances, a shared lease, or messages, from before and after the wedding.
One helpful note: as the spouse of a U.S. citizen, you would fall into the "immediate relative" category under 8 U.S.C. section 1151(b), INA section 201(b), which means there's no annual cap on how many green cards are available to you, unlike some other family-based categories that involve long waits.
If you're currently in the U.S. without lawful status, or your current visa is close to expiring, the timing and order of these steps matters a great deal and can affect whether you can adjust status here or need to leave the country first. That detail is worth reviewing with an immigration attorney before you file anything.
This is general legal information, not legal advice. An immigration attorney can look at your specific situation, including your current visa status, and help you choose the right filing strategy.

Frequently Asked Questions
Do I need a lawyer to file for a marriage-based green card?
No, it's not legally required, but the paperwork has strict evidence and formatting rules, and mistakes can cause delays or denials. Many couples use an attorney, especially if either spouse has any immigration history that complicates the case.
How long does a marriage-based green card usually take?
It varies widely based on whether you file inside or outside the U.S. and current government processing times, ranging from several months to well over a year. An attorney or a current USCIS processing time check can give a better estimate once your filing category is set.
What if we can't get married for a while?
You would simply file the I-130 after the wedding takes place. There's no need to file anything with immigration authorities before you're actually married.
