We are U.S. citizens (O.C.I.) holders and married for last 11years having no kid. We are planning to adopt a new born healthy nephew from India. Its my brother second boy. Both biological parents are physically and financially healthy. We did contact adoption agency they suggested baby doesn't fall under Convention Adoptee hence mentioned I-800 will not get approved by USCIS . We are willing to go back to India(Looks like only option left) for domestic adoption if possible. Our concern is if O.C.I. holders are allowed to proceed with domestic adoption in india and if that adoption is eligible to file I-130 after having legal custody of the child for 2years.Thank you.
