If I get married to a US Citizen, will I be able to file for a green card without the consent of my parents?

You do not need your parents' consent for filing an application for a green card, just like the law does not require you to obtain their consent for your marriage in this country. If your fiance has sufficient income to qualify as your sponsor on Form I-864 Affidavit of Support (or finds someone to become a co-sponsor), there should not be too many problems with your becoming a permanent resident. However, I would suggest that you stay in school until you get your degree and keep your F1 status. If you apply for adjustment of status 2 years or longer after your marriage, the process will be a bit easier, about $500 cheaper, and, most importantly, the green card you will receive will be a permanent one, not a temporary, conditioned on continuation of your marriage. Young marriages fall apart quite often. If your love does not last 2 years, you would still be legal in the U.S. as an F1 student and not be locked in a dead marriage by fear of deportation. Not completing your degree while your parents pay for it is not a particularly bright idea. Besides, it is very likely that your parents disapprove of your fiance partly because they think marriage would cause you to cut short your education; if you continue your studies after getting married, your parents might change their attitude towards your marriage and your husband.

Yes, you will be able to apply for a green card. Since you are over 18 years old, you are an adult and can make your own legally binding decisions. That includes choosing who to marry, when to marry, and applying for a green card. Make sure you stay in status until you are ready to file for your green card (i.e. stay in school).

As a 19 year old, you are above the minimum age to marry without your parents' consent and if you do marry your US citizen boyfriend, he can file a petition for you to get your green card. I will advise you to retain the services of s reputable immigration attorney for your case.

You can marry without your parents' consent as long as you are over the age of 18 in California. So you can also file for the green card.

You are no longer a minor and in most jurisdictions you are permitted to marry. Whether or not it will be a negative point on your immigration matter is a separate issue but you can definitely get married without the consent of your parents.

Yes you can file for adjustment of status after marriage to a US citizen. In California If you are over 18 years of age you do not need parental consent for marriage.
