For opening a Liaison office in India you need RBI approval. Such approval is for a period of 3 years, after which you can renew the licence for a further period of 3 years or opt for closure. For Closure you need to make an application to RBI.
Wholly owned Subsidiary is a Company registered under the Companies Act.
You will have to apply for closure of Liaison office and subsequently incorporate a wholly owned subsidiary.
