how easy (or hard) is it?

Re: how easy (or hard) is it?

he doesn't own a car, but i think the home they live in is in his name. He's been retired for a couple of years. My mom wants him to come here for the summer because he has heart problems and has trouble with the heat and humidity in Lahore. How long ago did you invite your father? I wonder if the laws have changed much.... Do you start the process from here or do they need to submit an application from there first? Where and how does it all start?

thank you for your help!
