Technically anyone entering the country is awarded the same rights and freedoms (such as given in the bill of rights ) regardless of whether they enter legally or illegally. But anyone outside the borders of the US is not subject to the laws or government oversight of the US Government (with the exception of citizens traveling or living in other countries). So yes. Technically yes. True.

I'll try to find a source.

"In decisions spanning more than a century, the U.S. Supreme Court has ruled that the Constitution’s guarantees apply to every person within U.S. borders, including “aliens whose presence in this country is unlawful.”

" But once here, even undocumented immigrants have the right to freedom of speech and religion, the right to be treated fairly, the right to privacy, and the other fundamental rights U.S. citizens enjoy."
