The official FAQ directs eligible joining family members to be included in the initial application for associated benefits. Keep the household information accurate from the outset and seek current instructions if it changes.
Coordinate family information with official stages
The process separates the processing fee, vetting and government gift after successful vetting. A private plan to pay later does not determine when family information should be supplied. Preserve official notices and respond to their actual requirements. Do not promise that adding a person at a later stage preserves the original timetable or guarantees the same outcome.
Official material describes processing in weeks, which is a description and not a guarantee; a qualified estimate from someone reviewing your file is more useful than either optimism or a flat claim that nothing can be predicted. The official page says processing should take weeks when the applicant responds promptly, but a visa interview is required, the applicant must be admissible and a visa must be available; the page notes that availability can cause longer waits for some countries. The program's timing, application steps and any changes are published by the government, and a decision this large should follow verification and independent legal advice, not a deadline someone else sets.
