Texas A&M and community college

I applied to tamu college station but was recently accepted to tamu Galveston for engineering. It is a program they offer where you go to Galveston for one year or so and then go to college station. The thing is that I really don’t want to go to Galveston so I was wondering how hard/easy it is to transfer to college station from community college. I am a high school senior and I am currently taking classes in lone star college system. If I decline the Galveston admission can I still reapply to college station when I am done with community college?
