I agree with Weswood about branding. IMO branding would generally be carried out as a punishment (branding thieves, rapists etc) or to mark property (e.g. cattle as mentioned by Weswood). None of that has positive connotations for the new citizenry. And to be honest, on a purely practical basis it doesn't really count for anything - if a non citizen wants to fraudulently pose as a citizen it would probably be as easy (if not easier) for them to get themselves branded than it would be to fabricate false papers.

I guess proving eligibility might be a bit of a challenge dependent on how many records survived the nuclear exchanges and could well be open to all manner of fraud (I've absolutely no idea what ASVAB tests are so they may address some fraud issues).

I'm not sure I follow the background as it is though...is this based on a Post Omega scenario where the 1st US Cavalry Division has been sent to Texas? Are people applying for citizenship if a breakway Republic of Texas or the United States? If the latter, does this mean that the 1st US Cavalry Division has defected en masse to said Texas Republic?

When you say that "verifiable prior US citizens are given automatic citizenship if requested' but also say that citizens "Must disavow any prior citizenship or loyalties to foreign governments" does that then follow that any US Citizens who accept Texas Citizenship must revoke their US citizenship? And if they don't they'll be removed as "Citizenship is NOT mandatory. But only Citizens will be allowed to live or operate in controlled Republic areas" so one must choose between being a US Citizen or a Texan citizen (and if one chooses the former will effectively be run out of town)?

All in all it sounds quite....draconian...not sure if that's your intention or not?
