It's not end run around 1A. 1A is a law protecting the people (and their various forms of organization) of the United States. Congress has every right to regulate or ban foreign entities of any kind for any reason from operating in the United States.
The rights enumerated by the constitution are human rights (“endowed by their creator”) and are not specific to americans.
Furthermore, the 1A is a restriction on the government and isn’t related to whether or not someone is a citizen.
There are lots of things congress is prohibited from doing under the constitution, including against foreign entities. Congress can’t ban a foreign religion operating in the US, for example.
So not "rights enumerated by the constitution." Which is why the degree to which the First Amendment provides protection does turn on legal status with America [1].
