Is it possible to live & work in Israel for x number of years and acquire a Israeli citizenship?

To answer you, a non Jew can Acquire Israeli Nationality by Naturalization

Adults may acquire Israeli citizenship by naturalization at the discretion of the Minister of the Interior and subject to a number of requirements, such as:

they must have resided in Israel for three years out of five years preceding the day of submission of the application;

they are entitled to reside in Israel permanently and have settled or intended to settle in Israel;

they have renounced their prior nationality, or have proved that they will cease to be foreign nationals upon becoming Israeli citizens.

The Minister of the Interior may exempt an applicant from some of these requirements.

Naturalization

Adults may acquire Israeli citizenship through naturalization. To be eligible for naturalization, a person must have resided in Israel for three years out of the previous five years. In addition, the applicant must have a right to reside in Israel on a permanent basis. All naturalization requests are, however, at the discretion of the Minister of the Interior.

Citizenship,Yes..

Nationality,No..

Israel is made for Jewish nation..Others can live and have citizenship, but they'll not be Nationals..

Because to join the nation you must be Jewish..

I am non-Israeli,but will be an Israeli someday.(hopefully)..

anything's possible

if you set your heart and mind to it

just renounce your current nationality
