My father is in prison and is set to be released in July. He is facing deportation and doesn't know what to do to stay here in the US, need help?

There is not enough information to determine if your father has a chance to stay here. Some criminal convictions can make someone ineligible for any relief from removal while others require the alien to obtain a waiver. You should take a copy of his criminal record to an experienced immigration attorney. This attorney can assess what can be done for your father.
