well you have no other option, do you? the only way the visa will be done is by you exiting. i don't know what help you're hoping for with this and i don't know why you're stressed about something totally out of your control; they hired you, they're working on the visa formalities and Insha'Allah it'll all be done without issues; go home and relax with your family until it's done and leave it to god; the reason why people stress about small things is because they think they are the ones who are going to make it happen; but in fact you are no one and it is god who runs your life for you and does what's best for you... you only have to try and give it your best and then leave it up god; you have done your part, now go home, laugh and play with your family and let god do the remaining boring stuff like the visa formalities... smile and chill buddy it'll all be ok Insha'Allah :-)
