Am I allowed to get married before I fix my parents' papers ? and would i be able to help my spouse get documents soon after?

There is a good chance that the cases will not meet – at the age of 18, you can marry and sponsor your undocumented boyfriend, but you cannot begin the sponsorship process for your mother until you are aged 21. By that time, there is a good possibility that your boyfriend’s case will be resolved. In the event that it is not, you would have to have enough in terms of income and assets to provide affidavits of support for your boyfriend and your mother unless either one has sufficient assets to ease the burden of support, or you have a joint sponsor who is a US citizen or permanent resident to take up the support obligation.
