The US Constitution only applies to US citizens and those others resident in the US. If you're not in the US (legally or illegally) then you're not resident and you're not covered. However, the US is also a signatory to the UN Declaration of Human Rights which is also an international self-executing treaty, and therefore of equal standing to the Constitution in US law. But whether the US Government recognizes the rights under that treaty need to be determined by court cases that haven't happened yet.
