Who is eligible to apply for a concealed handgun permit in Nebraska?

In Nebraska, anyone over the age of 21 is eligible to apply for a concealed handgun permit. This is because the state requires applicants to be at least 21 years old to legally possess a concealed weapon. Options B and C are incorrect because non-residents of Nebraska are not eligible for a concealed handgun permit in the state, and individuals with a felony conviction are prohibited from owning or carrying a firearm in most cases. Option D is incorrect because minors under the age of 18 are not legally allowed to possess a handgun in Nebraska. Therefore, option A is the only correct answer.
