EU citizen here, living in Germany.
In 2012 I traveled to Iran.
Last time I was in the USA, in 2015 (pre-Trump), some border officers asked me needless questions about my travels, and told me to write down the names and phone numbers of the locals I had met.
In 2019 (Trump administration), I tried applying for a ESTA to visit New York and was rejected due to the fact that I was in Iran in 2012.
I was wondering, now that Trump will be kicked out of the White House, if these restrictions will be eased and tourists that have been to Iran >= 2012 will be once again able to easily get ESTAs.
