Australian 309 spouse immigrant visa problem (husband is in Australia, children and I are in China)

If you can't speak English in the visa interview, they usually have an interpreter to help you, so don't worry. You can say hello in Chinese. Generally, investigations don't call in front of you. When answering the visa officer's questions, tell the truth and never lie. They just want to know whether your real intention to go abroad is consistent with the purpose of your application. Immigrant visas are generally easy to pass. Don't worry.
