Before submitting the application at the e-Registry, you have to prepare the certified documents that have to be submitted together with the application form (e-Form NN1). The documents should be converted into Adobe Portable Document format ("PDF") after certification and the file size should not exceed 3 MB. For the company’s accounts, the file size should not exceed 5 MB. To ensure the quality of image records of documents which are made available for public search, the page margins of documents should be set as Top: 1.27 cm; Bottom: 0.86 cm; Left: 1.06 cm; Right: 1.27 cm. Moreover, if a document is converted into PDF files through document scanning, you are advised to arrange for "black and white" scanning to produce a better image.
You can login the e-Registry [e-Submission Services > Online Submission] and select "Registered Non-Hong Kong Companies > Register a non-Hong Kong Company" to complete the registration process. During the process, you have to indicate the number and type of officers to be reported in the e-Form NN1 to facilitate the generation of the e-form by the system. You can then input the required data in the e-Form NN1 and Notice to Business Registration Office (IRBR2) and complete the registration process through a guided wizard. The e-form can be completed online or downloaded for offline completion.
For details of the requirements of documents and certification, please refer to the information pamphlet Registration of a Non-Hong Kong Company (pdf format).
