This is not sure but according to information from different forums and sources.@ramkris What if I plan to stay 6-8 months in India? What would be the procedure then?
1.
- Application form, complete in all respects, along with all relevant enclosures and requisite fee may be submitted to the Indian Mission/Post/Office in whose jurisdiction the applicant is ordinarily residing irrespective of the fact whether the same Indian Mission/Post/Office has issued the original OCI documents or not.
where they say you can apply oci from place you normaly reside.
2. If you still wanted to apply from india. you need to take an x-visa or entry visa on which you can stay 6 months and it can be extended with in india as many times. then you need to establish your address everything in India as if you are residing there then apply for oci after applying it may take more than 6 months also no one knows.
In your case if you are saying 6 to 8 months. If Iam in your place I would go for a short trip to nepal or srilanka at the end of 6 months and come back for next 2 months or more.
