My sister has settled in England. I want to go and see my mother. What procedures do you need at home? It is said that a passbook is needed. Do you need this passbook?

2. Your sister's current job and detailed address.

3. If parents are working, they need to show a letter of leave (it is very important to judge whether there is an immigration tendency).

4. Proof of deposit. It's best to keep a notebook, and it's best to show the transfer record.

5, you can provide fixed assets, such as real estate license, to prove that your life in China is also very good, and eliminate the tendency of immigration.
