You should apply for the All India Counseling process for the BCAT seat in Chhattisgarh.

Here's why:

• All India Quota: A certain percentage of seats in every state's medical colleges are reserved under the All India Quota. These seats are filled through the All India Counseling process conducted by the Medical Counseling Committee (MCC).
• Eligibility: You, being from Andhra Pradesh, are eligible to apply for seats under the All India Quota.
• State Quota: Chhattisgarh state counseling is primarily for candidates who are domiciled in Chhattisgarh.

Therefore, to increase your chances of securing a BCAT seat in Chhattisgarh, focus on the All India Counseling process. However, keep an eye on the Chhattisgarh state counseling process as well, in case there are any specific provisions for non-local candidates.

hope this helps you!!
