- This species is from a culture that follows laws or policies that conflict with that of the United Federation of Planets. They would have to subscribe to Federation ideals instead of that of their homeworld.
- This species has a history with time travelling or universe/timeline-hopping. If your character is from any time period or timeline other than our own, they will be bound by the temporal prime directive. They will only be aware of our timeline and their home timeline - they cannot be aware of, nor share details on, any other alternate timelines.
- This species is not a member of the Federation. In order for a character of this species to apply to Starfleet Academy, they will have required a letter of recommendation from a Starfleet officer ranked Commander or higher.
- This species is hostile to, or presently at war with, the United Federation of Planets. You will have to include extensive detail as to why they have chosen to leave their own people and join the Federation instead.
