Doubts regarding nativity?

Sir...I've doubts regarding the eligibility criteria for tancet...I'm a keralite by birth and did my schooling in kerala till 10th...but then we shifted to tamilnadu and I did my 12th and ug degree here in tamilnadu...we obtained tamilnadu ration card and voter id on aug 2010...Now I have a doubt on what my nativity actually is...Is it TN/kerala...???? While filing the application form I gave my nativity as kerala.....Will it cause any problem sir???? Since I'm learning here in tn for 5 yrs will I be treated as a tamilnadu candidate though I have given my nativity as kerala???
