Avoiding answering questions isn't conducive to honest discussion.
So, back to the beginning:
A resident or a citizen? I'm comfortable answering for you and saying you have a national citizenship somewhere in the world. We're not told we don't have such. We're told what the hierarchy is.
I'd also say neutrality is a myth. We aren't being neutral when we're choosing to decide according to the rule of our heavenly citizenship. This involves us in politics which is a big discussion with several definitions and categories to consider. In regard to your single example re: feeding homeless people, this article might be of interest for discussion

Also, in regard to your example, one could argue by submitting to the city law, you potentially disobeyed the wording of your heavenly citizenship in favor of your worldly citizenship or temporary residency (Luke6:30). And, depending upon all the wording and intent of the law of that city, it would be interesting to know more about it because the proliferation of such laws was more specifically to not feed the homeless, which has been contested as people try to figure out what to do about the problem. Your perceived work around would be an offense in many jurisdictions and if pursued you'd find yourself being firmly made aware you are involved in politics.
