I joined in January and was provided with ticket for all of my family and a cargo allowance. You have up to 1 year to use the joining ticket for your family should you chose to wait. Finding a school is a problem as well as it doesn't help to have all of the distractions during training. At the same time training often takes a long time here and it may not be an option to leave family on other side of world.
Currently Qr is giving permanent housing again. (Subject to change of course).
There are 33 countries that can get visa on arrival and it may be extended for 1 more month for 100 qr. Hopefully that is time enough to get resident permit and sponsor your family.
