Congratulations on your marriage plans! Getting married will not impact your LC.
The LC is filed with the Department of Labor and only contains your information. You will be able to add your spouse as a dependent at a later stage. Once the LC is certified, we will connect you with our partner law firm who will prepare the I-140 immigrant petition for you plus the green card applications for you and your spouse. At the I-140 and green card application stage, you will be asked to provide details about your marriage and spouse.
