I don't believe what the PM said and he may have said to please the NRI who went to Parvasi Bhartia Diwas.Even if they want to Merge PIO with OCI nothing was stated how they are going to do that and when they will do that. PM alone cant do that in few months and Government of India is busy facing Many Scams. 98% Miniters,MP, MLA are all corrupt. why nobody including PM or others said anything why now the Indian Consulates suddenly started collection of $ 175 for Cancellation of Indian passports and started giving a paper called Surrender Certificate? is that donation on the name of Surrender Certificate? what they have done or doing to Bangladeshi who daily enter India and then get Ration Card by paying Rupees 500 Bribe and then Get driving license by paying Bribe and then get PAN card and then Indian passport? Do they think that one cant get Indian passport again if one wants? One can get Birth certificate made with different date of Birth and place of Birth by paying bribe Or can attach affidavit for new date of Birth or place of birth and can get Indian passport again. Those who got US Citizenship knew that once they have got US citizenship they are not going to use Indian passport as it became invalid automatically as Indian constitution don't allow Dual Citizenship.
***If I am in OP position I will apply OCI for ALL the family members.
