This is an interesting development:
If she lied about her birthdate on any official form — a passport renewal or bank loan application, for example — Omar could be prosecuted.

One reason I'm skeptical:
Omar’s birthdate had been listed in the Minnesota Legislative Reference Library as Oct. 4, 1981, as well as on reference sites such as Wikipedia and in media outlets like the BBC, for the entire time she served in the state House and for several months into her congressional term.
This is easily verifiable, if true, and browsing Wikipedia's history shows that Omar's birth date has been listed since August 17, 2016, and it has always been 1982. So
someone in the media failed to do even some rudimentary homework.
Assuming for the sake of argument that it is true, however, then it's significant. She says she got American citizenship at the age of 17 and it's derivative from her father's naturalization process. If she was born earlier, in 1981, then she was no longer a minor at the time and ineligible for derivative citizenship.
If (and at this point I emphasize
if) she is in fact guilty of immigration fraud, then not only is her U.S. citizenship fraudulent, but so is her election to Congress. In which case it would fall on Congress to vote to expel her, per Article I, Section 5 of the Constitution.
