I think so. Maybe they want to make sure about our close relationship. We do not worry about it. But I still have something to ask. When my boyfriend came to China to meet me, we stayed together for almost three weeks. He wanted to buy a diamond ring for our engagement, but I did not want him to buy because I thought it was too expensive and I did not realize the engagement ring was important proof of our close relationship. But he met my parents, my family and my best friends, and had dinner within my family to show that we were engaged. Although we have lots of other proofs to show our close relationship, we do not know if the engagement ring receipt is the necessary proof. If they ask about it, what should we explain? And after they mail our file to GZ, does GZ contact my company to check if I am really working there? Because I moved to another city, I do not want to make our case delayed again due to my moving. Thanks.
