Relating to United States citizenship requirements for the licensing and employment of peace officers.

HB 4257 requires peace officer license applicants in Texas to provide proof of U.S. citizenship, with the requirement applying only once per license (renewals don't need re-submission). It directly affects individuals seeking peace officer licenses and law enforcement agencies hiring them, mandating agencies verify citizenship before employment. Exceptions allow hiring for legal permanent residents who've applied for citizenship, or honorably discharged veterans with at least two years of military service. The bill adds these verification steps to existing licensing and hiring processes under the Texas Occupations Code.
