No. If you are not a US citizen, you don't have a vote, and therefore you do not have a representative in Congress.
That said… I doubt they have any capacity to actually check if callers are US citizens.

The real way to do it, which I've written about occasionally for the last decade, is to identify the worst surveillance offenders of each major party. Narrow down the list to ones who are electorally vulnerable (this excludes Feinstein, for instance). You'll need to spend millions of dollars on ads reminding voters how thoroughly the incumbent disrespects the Constitution. Also encourage contributions to the incumbent's challenger. Only do this where you're likely to win. Committee chairmen would be ideal. Be thoroughly non-partisan and focused only on surveillance.
Once you do that, and have a Cantor-like upset against the pro-surveillance, anti-privacy incumbent, suddenly privacy will be taken far more seriously on Capitol Hill. Politicians will respond better to this than a useless $1,000 PAC contribution.
