The constitution does not explicitly grant due process to non-citizens, but statutes and judicial rulings since have generally enforced that non-citizens have most of the same rights as citizens when it comes to criminal investigations. I don't think we know whether or not there was probable cause to believe a crime had been committed. We don't even know what sort of search order was granted. For example, maybe the account owner is not the subject of the investigation, but the account is believed to contain information that would be relevant nonetheless.
