1. Everyone must send in their CHL 100 - this proves you have taken and passed mandated class and shooting proficiency given in person by a state certified instructor. (the instructor does not do this, it is the responsibility of the applicant)
2. Digital Fingerprints must sent in - the Digital Fingerprinting vendor will send this in, the applicant only receives a receipt, which the applicant keeps for his records. (in the rare case that you qualify for inked fingerprint card, the applicant is responsible for sending them in).
These two documents are required for all applicants in addition to the application.
Any arrest or criminal history greater than a class C misdemeanor needs to be reported on application, you may have to send in additional documentation to support this history, if you have this it is a good idea to scan and send it in before the State asks for it.
If you claim (over 60) senior citizen discount (1/2 normal fee) the state will use the proof of that from your State Drivers License or State ID.
Veterans will prove their status by sending a copy of DD214. This can be done online or by snail mail.
Indigent discount will be proven by sending IRS statements or another acceptable proof of low or no income.
LEO, officers of the court, or any other discounts will be proven by provable documents of the department involved. It is still the responsibility of the applicant to make sure these items are sent to proper DPS address.
Active military status or those discharge honorably within 360 days must send State their documentation to prove status.
The State will allow any applicant to claim any discount, as long as the applicant can justify the discount with proper documentation.
The State does not take responsibility for finding the applicants discounts. The State only verifies the authenticity of applicant documents to support claimed discounts.
If the State notifies the applicant of additional needed documentation, the applicant has 90 days to respond with the requested documentation or a viable request for more time, before the State closes the applicant file. The State will not notify the applicant to send in the CHL 100 or to get fingerprints. (This is considered known documentation needed for all applicants)
If an applicant is eligible for more than one discount, the applicant chooses which one is best for them, only one discount may be used by applicant.
Now that this is as clear as mud. I am sure I left something out. Remember the applicant need not worry about anything that does not apply to them.
P.S. Anything that is done by snail mail must have all signatures notarized.
