My husband applied to me in San Francisco. Does anyone who has been there know what problems will be encountered when going out to Guangzhou to meet the immigration officer? What details should I pay attention to? I just immigrated to San Francisco, and the immigration officer may ask you questions based on the information you submitted. First of all, don't be nervous. If you are nervous, that's all right. You should know how to say it. She asked me then. How did we meet? Did my husband send me money when we got married? Send it every few days. You should try to bring photos, letters and money orders of your daily life. Choose some natural and intimate photos. I will bring photos of my husband and my niece. She also asked me who it was. I answered her easily. That's all she asked me. At that time, she was expressionless and fierce. I don't think it is good. When she tried to hand me the paper, I was very scared, because a person next to me just took a piece of paper with a similar color, as if to say no. I thought it was over, so I quickly told her that if you need any information, I can still provide it. (Because I've been buying insurance for myself, and the beneficiary is my husband) I have it with me. She said yes. I'm relieved. This is just my situation. Everyone will be a little different, please refer to it. Take it easy. I wish you success and hope you can come here as soon as possible.
