Maybe it exists but has anyone thought of throwing a web app with a questionnaire to determine eligibility.

It seems like the different routes to citizenship are fairly straightforward and if there was someone with a little bit of tech savviness you could build a multiple choice/ yes or no quiz that could then spit out eligibility and which route to take. Maybe this has been discussed before but thought I would throw that out there. Then it could be auto posted to each post that is asking about eligibility.
