Since you entered without inspection, in order for you obtain your residency, you will have to go through consular processing. However, based on your age, you will have to present a waiver for your unlawful presence in the United States. This is not an easy strategy and can be risky since it's not a guaranteed process. I would recommend that you marry and accumulate evidence of extreme hardship to your spouse before you proceed with Consular Processing. It is critical that if you decide to proceed that you consult with an immigration lawyer.
