JERUSALEM, Aug 1 (Reuters) - U.S. observers are in Israel this week to discreetly assess conditions at its border crossings for Palestinian-Americans as part of an emerging Israeli-U.S. visa waiver deal, four officials said.

The officials, who declined to be identified by name or nationality, said the delegation visited Israel’s immigration office on Sunday, Ben Gurion Airport on Monday and would on Tuesday tour checkpoints on the occupied West Bank’s boundaries.

In return for visa-free access for Israelis, Washington has demanded that Israel provide reciprocal unfettered passage for Americans, regardless of their background.

That would overhaul travel rules for tens of thousands of Palestinian-Americans who live in the West Bank, as well as, potentially, those from the United States, some of whom complain about harassment or travel bans when trying to visit relatives.
