Interviews are whenever it is convenient and possible to have them. In some missions they rarely happen. On my mission they generally happened on a regular basis, except that my mission had some islands. The mission president didn't fly out to the islands frequently. There are other missions which are similarly expansive and make interviews difficult. Why do you ask? If you're a missionary, well, you shouldn't be on AnswerBag. But then, if you're a missionary who wants to go home ... then perhaps I shouldn't be surprised. (That said, if you're a missionary, get off AnswerBag.) Since you don't seem to know how often to expect interviews, then, if a missionary, I'd predict greenie and... having companionship problems. (Otherwise, you'd ask your companion.) Companionship problems, of course, might make one feel like going home. I had a jerk companion once. It was the pits. I was the most depressed I'd ever been before in my life. I also achieved one of the two greatest accomplishments of my mission. My next companion was great. It's amazing what a difference a good companion can make. Looking back, I wish I'd communicated better with my mission president about what was going on. I felt like I'd be a whiny missionary if I complained, but that was just stupid. If you're not a missionary, it's a very odd question to be asking. Maybe you have a missionary you're trying to "help out"? My advice. Stop "helping" and tell him to talk to his mission president and (assuming the companion isn't a jerk) his companion. There is order in the Lord's kingdom and there's a reason for it. So, the process? Talk to the mission president. Let him know what's going on. If the missionary in question is suffering physically or mentally in a way that can't be coped with, there is no reason to wait for an interview. Call the mission president and let him know what's going on. If one is the companion of such a missionary, I highly recommend the same course of action. Such situations that I've been familiar with have resulted in a neutral discharge. (ie. neither honorable nor dishonorable) Testimony problems and just plain fickleness are rather dishonorable. This is not a statement of official policy, this is just the few situations I am familiar with.

I don't know about the interview schedule but if a MIssionary wants to go home, all he has to do is tell his mission president that. You re not required to give a reason if you do not want to. It is your life and you are free to leave whenever you choose. The mission president will try to stall but if you really want to leave, simply stand your ground. You can be on a plane back home with 7 days normally. . And there is no such thing as a dishonerable release. People will make you think so but that is only their peronal judgement against you. All in all, a mission is not for everyone and you are free to choose as always. It comes down to your relationship with the Lord and how you feel about it. . That being said, a mission can be a wonderful thing if you work through any issues you are having. If you feel you can do it then by all means, stay! If not, there is absolutely no shame in coming home. Don't let anyone tell you different! :)
