Criminal justice is usually not considered a “solid” or transfer major by top universities (more like prep before you become a police officer or a DoC officer - Criminology is the legit major combining Psychology and Policy, and it’s usually selective.)
Is there a way for you to be listed as undeclared/transfer pathway?
I would try to switch out of the CJ major. If sth like undeclared/transfer pathway isn’t possible, what about History or Spanish? (Those would be considered legit.)
Does your CC offer advanced courses in foreign languages + courses in history and philosophy? (European, US, and non Euro/non US history would be core classes for IR, and philosophy if un necessary for IR is considered evidence of rigor and ability.)
IR will require one foreign language (perhaps 2) at a high level requiring study abroad, so advancing one and starting another, both related to your geographical area of interest, would be useful.
Depending on your area of interest the language (s) will vary - FYI if Latin America, Spanish and Portuguese; if Western Europe, French and German or another European language; if Eastern Europe, Polish and Russian, Romanian, Slovak, Ukrainian, etc; if Russia, Russian and Ukrainian or a language from their sphere or ex sphere of influence ; Sub Saharan Africa, French and Swahili or Hausa; if the MENA area, Arabic, Hebrew and French; etc.
Some of these languages can be difficult to find so don’t worry if your CC only offers Spanish and one other
the key would be to go as far as you can in one language to show ability (and perhaps to get started in another language but that’s less important).
Look into Critical Language Flagships: these programs lead directly to jobs in IR/IR related fields.

Unfortunately there aren’t any in Texas 
Among those offering merit scholarships, there’s
ASU -where you can combine the Chinese flagship and ROTC

UArizona has a Portuguese flagship.
Portland State has a Russian flagship

Ole Miss has Chinese and Arabic Flagships

West KY has a Chinese flagship
That’s about it for universities with Critical Language Flagships that MAY offer merit scholarships.
Is there another CC you can commute to so you could take the Poli sci, foreign language/lit/culture, and history courses you’d need?
Beside AU, GWU, G’town, good colleges for you to look into (due to academic strength and excellent FA) would be Penn, Dartmouth, Middlebury, Tufts, Hamilton, Macalester. Ole Miss (Croft Institute), UGA, UDenver, Spelman also have good depts and connections but their FA is likely to be lousy for a transfer.
Look into Kalamazoo, St Olaf, Grinnell, Dickinson for colleges that are strong in IR-related fields& Language/Culture and offer FA.
St Olaf’s Global Semester may be of particular interest as well as Dickinson’s programs.
