Thanks everyone for your reply. I have heard that it can be a long process to hire someone as live-in (not sure if I am right). But, if my wife gets a job at a short notice and my child needs to attend school, then, if we need to hire a nanny (part-time) say from12-5pm, can we do it directly through agency, so that we will be able to find someone sooner, rather than sponsoring that takes a long time (even months). Please let me know. I hope I made myself clear and my apologies if I my querry was not understandable.
