Most rights in the US constitution, including the free speech right, apply to foreigners physically present within the US as well as to US citizens worldwide. I do wonder if those rights would apply to those foreigners who apply for a US visa while physically in the US (or who are there during the relevant processing stage). Possibly yes because of their location at the time, but possibly not since the visa is not finally adjudicated until the foreigner leaves the US for a visa interview.
