What policies made persecutions of Jewish German citizens official?

There were a number of measures taken.

Explanation:

The Law for The Restoration of The Professional Civil Service was passed very soon after Hitler came to power in April 1933. This excluded non-Aryans from the legal profession and civil service.

In 1935 the Nuremberg Laws were passed. They had two main components. Firstly it made illegal, any form of relationship between Jews and Germans.

Secondly the Reich Citizenship Law stated that only Germans or those with German related blood could be German citizens. This effectively excluded German Jews from any form of participation in German society.

i think the answer is a and i hope this ; ))

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
