FP Notice came to old address INS office-Please help

[vinmad]

I received FP notice from INS today. Here I have a question . I used to live in Hartford , CT.
I moved to Atlanta, GA in October first week. I sent change of address to INS in October. Now I received FP notice appointment with Hartford, CT INS office. But I am living in Atlanta, GA.
I don\'t have any problem in going to Hartford, CT .
Can I go Hartford ,CT ? or Do I need to change appointment to Atlanta. If so, how to change?

Please advice. Your help would be greatly appreciated.

Thanks
