A mission at 18 isn't for everyone.Your son is an adult and it's up to him when/if he goes on a mission.he has plenty of time to go on a mission and like other posters have said,going to college will be a good preparation for him.One of my sons went at 18,had to get special permission at the time,he was ready.His brother was not ready at 18,he went when he was 19 ,he decided when to go. Pressuring people about anything often has disastrous consequences,I know several YSA who have decided not to go on missions and are less active as they weren't ready for a mission and were terrified at the thought.I know other people who went after they had got their degree,it was right for them.The bishopric sounds very well meaning but you know your son better than them.
