女婿可以担保岳父岳母做父母移民么？

可以的 和你做担保人没什么区别。要提供关系证明，比如你们的结婚证明， 还有你和父母的亲属关系证明。

Your child's partner (aged 18 or over) is also eligible to sponsor you if they live with your child and are settled in Australia as one of the following:

    * an Australian citizen
    * an Australian permanent resident
    * eligible New Zealand citizen.
