My friend got H1B from Osaka. He said the got namaste from the visa officer as greetings before he said good morning. Then the officer asked how long do you want to stay in the US? Is that salary OK for your family? Is that salary higher than you have in Japan. Living cost in US would be less than in Japan, so I hope you will enjoy living in the US. Goodluck with your research. Your passport will be posted to the address you have mentioned. Good day! My appointment is on next monday. Will tell you about my inteview. Seems like visa processes in the US consulate in Osaka is fair and smooth. What we need is just our passport, photograph, 100$, H1B approval letter, letter of offer and alien registration card issued by Japan government. Goodluck guys!
