16 Commonly Held Amish Myths Busted!
7. Myth - Only Amish People Are Allowed In
Another very common myth is that only Amish people can join local communities, presumably from other Amish areas and thus inbreeding is rife due to this enclosed blue blood system.
Whilst I personally have indeed seen some rather... erm, strange looking young Amish men whose features do betray a life of family love, anyone can join an Amish society. That is if they're sufficiently determined and willing to leave material goods behind and put the requisite work in. It may take local elders some convincing of such a commitment but if successful, a married couple or even a single person can join the clan.
A person intending to convert to the Amish church should have cash to buy a farm as well as some serious farming chops so it's no cakewalk to regress to Amish life.
