I don’t think the timeline is a year if you send all the required paperwork. We just did the dependant sponsorship and they told us 10 months but it took them under 6 months from the day we submitted to when we got the visa. They received her application on February 1st and my stepdaughter will be here this Friday.
Unfortunately it's been a year were June 2017 applicants lol. My husband and step child I filed for. Waiting to see if I hear something. The landing fee hasn't been ask either.
