父母一方持有143签证准备递交另一方配偶签证的申请人
如果父母一方持有143这种父母签证，本来准备5年后申请配偶签证的人，可以考虑提前递交配偶签证。这样在境内就可以拿到过桥签证。
这种父母143签证持有人之所以不能立刻担保配偶，主要是受到了移民法Reg 1.20KA的限制。原文如下
Reg 1.20KA Limitation on approval of sponsorship—partner (provisional or temporary) or prospective marriage (temporary) visas
(1) This regulation applies if:
(a) a person is granted a specified visa on or after 1 July 2009; and
(b) the person seeks approval to sponsor the relevant applicant on or after 1 July 2009; and
(c) the person was the spouse or de facto partner of the relevant applicant on or before the day the specified visa was granted to the person.
(2) The Minister must not approve sponsorship by the person of the relevant applicant within 5 years after the day when the person was granted the specified visa.
(3) Despite subregulation (2), the Minister may approve sponsorship by the person of the relevant applicant:
(a) if the relevant applicant had compelling reasons, other than reasons related to his or her financial circumstances, for not applying for a specified visa at the same time as the person applied for his or her specified visa; or
(b) if:
(i) the relevant applicant applied for a specified visa at the same time as the sponsor; and
(ii) the relevant applicant withdrew the application for the specified visa before it was granted; and
(iii) the relevant applicant had compelling reasons, other than reasons related to his or her financial circumstances, for withdrawing the application for the specified visa.
移民法规定 820.22 Criteria to be satisfied at time of decision 是一个在决定时候必须满足的条件
820.221A
Unless the applicant:
(a) is, or has been, the holder of a Subclass 300 (Prospective Marriage) visa; and
(b) is seeking to remain permanently in Australia on the basis of the applicant’s marriage to the person who was specified as the intended spouse in the application that resulted in the grant of that Subclass 300 (Prospective Marriage) visa;
the sponsorship of the applicant under clause 820.211 has been approved by the Minister.
Note: Regulations 1.20J, 1.20KA and 1.20KB and 1.20KC limits the Minister’s discretion to approve sponsorships.
我们知道在签证递交时间和移民局决定时间就会有一个时间差。按照目前配偶签证的审理速度，至少1年的时间。所以如果客户的父母一方的143签证已经下签超过4年，是可以考虑利用这个时间差来递交另一方的配偶签证的，下签的时间越长，这个方案的风险越小。最坏情况是由于移民法Reg1.20KA 导致法条820.221不能满足，那么也可以进一步上诉到AAT，用AAT上诉的时间来满足这个法条的。
