 The blacklist did not affect anyone's ability to make aliya, since that is controlled by the Law of Return and not through the Rabbinate, but it did impact on people's ability to get married in Israel.The situation became even more difficult when it was revealed that Haskel Lookstein, an Orthodox rabbi, was included on the blacklist and some of his students were not permitted to marry in Israel.Lookstein was the officiating rabbi at Ivanka Trump's conversion, and created some difficulties between Israel and the United States since this was revealed shortly after the election of her father to the presidency.
