With power
 comes an obligation to those you 
have power over

   We often speak of serving your constituents, referring to the people from the state or district that elected you. And, while they would be the primary constituents, you cannot escape your responsibility to any who be impacted by the decisions you make. Fairness of mind, and fairness of character charge you with the responsibility to be fair to all who will be impacted by your decisions.    You should love all mankind and not want to wrong or harm or do injustice to anyone. So, the laws you make should come only after you consider on what they will do to others, on whether they will reflect a love of all those who will be impacted. Love of all mankind means love of all mankind. 
   So, what then of the immigrant? I would suggest we have an obligation to them. Whatever laws we make, those laws should be fair to them, and do them no harm nor injustice. More: When possible, the laws we make should help and care for them, for that is the measurement of love.
