1. If you can show that your residence falls under the Milan consulate, they may not have a problem accepting your application. At the end of the day, the consulate gets to decide.
2. You can travel provided you have the job starting and the employer will pay you after you enter the US.

Should be ok in general. But the VO could ask you to get corrected as Kumar finds its way into security checks.
