I think that the same premise applies today as it did back then - people come to "the New world" (although it is no longer new) because they are seeking an escape from something that they are leaving behind in their country of origin.Therefore, the push is to leave a bad situation. The Puritans were separatists (meaning that they had ideas that were not in line with the majority - in this case religious ideas - so they separated). They were being persecuted for their beliefs, so the push, for them, was to escape. Settlers in the Virginia colonies, on the other hand, had a different push - economics. They were n ot making as much in Europe and the new world was a land of economic opportunity. The pull factors, then, were freedom and opportunity. These are the same factors that drive immigration today. Many immigrants feel that the societies they live in are oppressive, the rules are unfair, the government is not doing its job. Others feel that America is a land of economic opportunity. In either case, the push is to get away from a negative situation, and the pull is a possibility of a more positive life.
