Can I get married while in the process of becoming a citizen?

There is no restriction on getting married while waiting for your naturalization interview. (I assume that you did not immigrate through marriage and are applying under the three year rule). You can apprise the naturalization examiner of your change of circumstance with documentation of the marriage (marriage certificate) at the time of interview.
