Hello, I was wondering if changing my marital status during the sponsoring process affects my parents getting their citizenship

I will assume that you are sponsoring your parents for the green card, and not for US citizenship. In such case, your marrying during the petition process will generally have no effect on your parents’ eligibility to immigrate. That being said, you are still liable to provide I-864 affidavits of support for each parent under which you will have to meet government financial guidelines. Your wife would count as one of your dependents. If she makes money, you could add her income to yours to bolster the support for your parents. If she is not working, the amount of earnings and assets that you have would have to be enough to cover one more person, your wife.
