Yes, your daughter's birth certificate should be considered as proof of nativity in Telangana.

While a nativity certificate is often preferred, in many cases, a birth certificate is accepted as sufficient evidence of nativity. Especially if both parents were born in Telangana and your daughter completed her education there, it is highly likely that her birth certificate will be considered as proof of nativity.

However, it's always recommended to double-check with the TNEA authorities to ensure that they will accept her birth certificate as proof of nativity. You can contact them directly or consult the TNEA guidelines for specific requirements.

If there are any concerns or questions, it's best to address them proactively to avoid any potential issues during the admission process.

I hope this information helps you.
