You filed in April right?
The trick is to sit back and wait! They couldn't possibly give you any information on your case so early.
There are no shortcuts unfortunately.
But if you check some timelines on here you'll see folk are still waiting that filed over a year ago.
You need the patience of a Saint or of Estadia, Zeenusah and countless others. You may want to look up their timelines on here.
Good luck!
