Usually the first issue year will be restricted to business & sporting use. After that, given no issues, they will upgrade to unrestricted LTC.
You're best bet is to document an active "credible threat" or that you have been threatened or are a victim, if you want unrestricted. Saying it's your right under the 2nd will get you nowhere.
After you file your $100 non-refundable fee, you will be given an appointment for an interview, at which time prints and a pics will be taken.
Subsequent renewals are $100 p/year, but you will not need another interview for 6 years and can be done by mail.
Mail the renewal early, I usually send mine in 6mo in advance to be sure to have it. Both times I waited 'till 90days in advance to renew, my license showed a month late. You CANNOT carry if you do not have a current permit, saying it's in the mail or in process won't work.
If you let it expire, you will need to restart the process.
