Overseas investment restrictions require approval for certain activities and limit funding sources and subsidiary layers. Residents are prohibited from making ODI in real estate activity, gambling, and rupee linked financial products without approval. ODI in recognised start ups must be funded from internal accruals or, for individuals, own funds. Residents must not make financial commitments that would result in structures with more than two layers of subsidiaries, subject to exemptions for banking companies, registered systemically important NBFCs, insurance companies, and government companies.
