It only took 1 week after submitting the application to get the visa.
The application and requirements are the same as when you applied for spouse visa but this time you will be the sponsor to your son. If this is not possible, your husband could be also be the sponsor.
We included 3 letters of sponsorship, from my wife as sponsor, from me as co sponsor and last was from her mother who had been looking after her son while she was away. Each letter explained the situation regarding the sole responsibility of her son.
Good luck with your application
