Hi,
In Israel, immigration officials put on sticker on the back cover (outside cover) of my passport. I took the sticker of, yet the glue from the sticker is still there. You can no longer see the sticker, but you can see that a sticker was there.
1) Could this prevent me from travelling to certain Muslim countries?
2) Could the glue on my passport make my passport no longer valid -- forcing me to get a new one?
Thanks a lot,
Max

I have glue stains from various stickers on my passport cover, usually from airline baggage stickers and some security thing I got in Russia, so unless it's in the shape of the Israeli flag or something, you'll be fine.
