bubka,
from where do you take those directions?
ACS can obtain a court order and take away the children by force. In fact Slamming the door on them will give them more evidence that you are hiding something from them.

No they cannot without proving to a court the children are in immediate danger.
And you absolutely do have the absolute Constitutional right to keep them out of your home for any or no reason at all. It is called the Fourth Amendment to the United States Constitution. And the right is absolute. You need not explain why you don’t want them in your home. And excersizing your right under the Constitution does not give them any thing to hold against you under the law.
They must go to a court and prove to a judge probably cause against you to get a warrant to do anything. Without them being able to demonstrate that to court, they are powerless. And you can keep them out of your home and refuse to talk to them.
