我现在是H1B，之后要去澳大利亚开一个会，现在在折腾签证。
看到这个网页上说 https://www.border.gov.au/Trav/Visa-1/600-/Visitor-visa-(subclass-600)-
Tourist-Stream-document-checklist
还需要
Certified copies of birth certificates for you and any other person included
in the application. The certificates must show the names of both parents of
each person.
这个大家都是怎么弄的啊
