Many thanks for your help.
I am a US Citizen and I want to file forms I-130 and I-485 for parents so that I can start their green card process.
Unfortunately, they both don't have their birth certificates. They both have visited USA and have the multi-entry visit visas. They both have Indian passports.
What is an alternative acceptable form that I can provide with my application packet if I don't have their birth certificates?
Mom and dad reside in Mumbai, India, but they are visiting me in US currently.
Mom was born in India
Dad was born in Pakistan.
Greatly appreciate your help.
