Of course, it is reassuring to bring the real estate license with you when you face-to-face sign. Your real estate license is mortgaged to the bank. When signing face-to-face, it is best to have the mortgage information of the real estate license issued by the bank, otherwise you can't easily say that you mortgaged the real estate license to the bank. When someone was interviewing for a visa, the visa officer asked if he had a real estate license, and replied that he was doing it and refused the visa immediately. The visa officer thinks this is dishonest. So pay attention to your own situation.
Have a nice trip.
