I am an Indian national living in London. I need to travel to Israel for work. I will need to apply for a visa but I have been told that it will be stamped in my passport. I have read that Israel knows of the problems travellers face in other Arab countries so they issue a paper visa but the embassy in London told me that it will be stamped in. I travel often in Middle East for work and I do not want any issues in the future. Please advise.
