What should I do if I immigrate to Hong Kong to buy a house and haven't got a real estate license?

If the certificate of immovable property right has been processed, but it has not yet been received, the original ID card should be notarized in advance with my ID card and Hong Kong and Macao ID cards, and it should be collected with Hong Kong and Macao ID cards and notarial certificates. If you have not applied for a property right certificate, you should first notarize the purchase contract and Hong Kong and Macao ID cards, then apply for a certificate with Hong Kong and Macao ID cards and collect it with them.
