Finally, I was able to get my Portuguese citizenship card and passport as well after a month and a half long process. I am posting the entire process which I went through in New Delhi India Portugal Consulate.
I emailed the consulate for appointment and documents, so they replied there is no need for appointment, the application are processed on first-come-first-serve basis at their office with all applications accepted until 12 PM and rest will be asked to come next working day.
They confirmed that I have to bring following documents for Citizenship Card Cartao de Cidadao application :
- Portuguese Birth Registration, usually called
- Indian Citizenship proof - meaning - current valid Indian Passport
- Permanent address proof - should match the one mentioned in Indian passport, I provided my bank account statement and driving license
- 2 recent passport size photographs - usually 4.5cm x 3.5cm
They also asked for my Power of Attorney which I have sent to my lawyer in Portugal for my birth registration. This is mandatory as per them, so please ask your lawyer/agent to provide it to you before you visit the consulate
After this, I paid the citizenship card application fee, they took my photograph and finger prints.
They told me it will take 2 weeks for the Citizenship Card Cartao de Cidado to arrive to their New Delhi Office.
After 2 weeks I kept chasing them for response about it but they responded to me after 3 weeks.
So I went again there, collected my Citizenship card Cartao de Cidadao and at the same day applied for my Portuguese Passport, no need for any appointment this time as well.
So after 3 more weeks arrived my Portuguese passport at their office. This time also I had to keep sending them emails about it for multiple times.
