Usually, you don't need to provide a real estate license to apply for a visa, but you need to provide other relevant documents. These documents include income certificate, work certificate, air ticket reservation, etc. Whether the loan page is private or not depends on the specific regulations of the state and banks. Generally speaking, loan information is part of personal privacy, but not all countries require detailed loan information as a necessary condition for applying for a visa. If you are not sure whether you need to provide loan information, it is recommended to consult the local embassy or consulate or relevant departments to get a more accurate answer. When dealing with sensitive information, we should abide by laws and regulations and ethics, and respect the rights and privacy of others.
