There is not much really you can do to speed up this process.If you already filed then its just a waiting game . Unless there is some specific circumstances that would allow the process to be shortened you really got to wait.Most people do it the other way though. They apply for those once their loved ones are already here on tourist visas. That allows them to at least vist here first.But your best bet is to contact an immigration attorney !Good luck!
