I am a worker with an E-9 visa. The employment contract for 4 years and 10 months will be expired soon. However, my employer said that he or she can extend the visa for one more year. I also want to work more. But it's been too long since I've been to my hometown, so I want to go back to my home country and rest for a while. Can I go back to my home country to take a break before my visa extension? Or do I have to apply for a visa extension first?
