If you are curious and want to see a helpful comment I added (a little late): to comment and answer on this page
I am going to travel to Israel at the end of the year for one week.
Somewhere I read, that I could get problems with a stamp from Israel in my passport when traveling to the US again.
Also I read, that I could get the stamp on a separate paper (Though I would need two pieces because one is going to get taken away as I enter Israel at the airport).
I'm from Germany and visited the US for the first time this year and wanted to visit the US in maybe two or three years again.
Does anyone know if I'm going to face any problems at the border with a stamp from Israel?
