The local sections are primarily divisions based on language. The moderators of each local section are allowed to set different standards for how fluent your posts have to be, but you should never be excluded based on residency/ethnicity/nationality.

India is unusual because they mainly speak English, and also they don't currently have a local mod. I suppose that as long as your posting is on-topic and the regular posters in that section don't get annoyed, it should be OK.
