How long is a Nebraska Firearm Purchase Certificate valid?

The Nebraska Firearm Purchase Certificate is valid for 3 years. This means that it will expire after 3 years from the date it was issued and will need to be renewed. Options B and C are incorrect because they suggest that the certificate is valid for a longer period of time. Option D is incorrect because it suggests that the certificate is only valid for 1 year, which is not the case as stated by the correct answer A. It is important to keep track of the expiration date of your certificate to ensure that it is renewed before it expires and remains valid.
