Recently a Palestinian guy who applied for Harvard has been in trouble when a CBP officer saw his Facebook account and the friends of the guy (not himself) shared anti US-propaganda stuff, and despite of it not being a crime, since it was done outside the US (that's not the only reason), CBP officers, power abusers as they were, shouted aggressively against him in a room asking for explanations and eventually sent him back to Palestine, but in an other instance the guy won a sort of appeal and he succeeded to get at Harvard in time.
An advice that I might give to you, is that if you have a website that parodizes about the US, just don't tell them that you have and end of the story, because you'll only get in trouble due to some US officials patriotic bigotry, and moreover if you don't tell them that you hold that side, on which basis can they suspect if you have any website whatsoever? You're not bringing it.
Another advice, if you have any other account, just log out from your phone and then re log-in after, because they'll make your life hell for every silly thing they may not like either for personal reasons or political ones. Just play smart.
EDIT: Send the link to your job employer and delete it from the portfolio, you don't need to show your project but only to say that you're good in that field. It's also in interest of you not getting copied and getting succeeded over unjustly.
