What are the advantages of having a sponsor code instead of a paper form (my sponsor has used an electronic form)?
If your sponsor in Norway has filled out an electronic sponsorship form and you include a 4-word sponsor code with the application (along with other relevant documentation), we will normally not need to collect any further sponsor information. This will usually cut down on the time needed to process the application.
If the visa application does not include a sponsor code or documentation showing sufficient funds, you should expect it to take longer to process the application because the immigration authorities will have to verify the information shown in the paper sponsorship form.
