Question: Asking my company to start GC app

I am planning on talking to my boss about GC app. My company doesn't have many foreigners. My boss probably never experienced GC app before. I talked to company attorney, who said it is good to start early but of course it is up to my boss because he has to pay for it. My boss went to talk to the company attorney. Then he said he will sit down and talk to me about it to get clear of things.

If i discuss it with my boss,  how should I persuade him to start it ASAP?  I haven't been working there long, a little more than half a year. My performance is fine. My boss is satisfied so far. 

Thanks!
