Would like to apply to Kellogg and Chicago (I live in Chicago and don't want to move) to get an MBA in marketing management and international business. Work now with russian companies doing outsourcing, feel lacking systematic knowledge.

What are my chances? I'm concerned with my age and work experience.

PS. I can answer why now MBA: 1st came 5 years ago to USA and was busy with my baby. Then some time took to adapt to different cultural and business environment. Now feel that it's right time to pursue MBA.

Thanks in advance
