Money does seem to be the only way to get even a hint of policy change from Washington, but the trend line of public opinion is opposite of what you suggest. Until around 1995, immigration restriction was overwhelmingly mainstream in the United States and still commands a strong plurality.
I'd further point out that the overwhelming majority of the moneyed interests still stack up on the side of permissive immigration policies. It is, after all, capital that benefits from a global free market for labor and an expanded consumer base. It's just about the only thing the Koch brothers and Soros can agree on.
