在处理客户的很多咨询中，我常常感到对移民局程序的了解有时候比法律更重要。
比如如下问题的答案，
1 客户现在已经申请了143父母移民签证，但是想通过转864签证获得过桥签证，在澳洲长期居住。这种情况143签证已经排队的时间可以带入么？
2 签证上有不能境内续签的no further stay 条款，如果在澳洲境内申请494签证？
3 学生课程提前毕业， 学签时长还有超过1年，这种情况会被移民局取消签证么？
4 由于移民局系统原因，申请人没有及时递交签证，移民局会承担责任么？
5 递交了难民签证，多久会遭到拒签，拒签后上诉，多久会开庭？
这些问题的答案，书本上没有，法律上没有，只有在不断的和移民局局日常博弈中才能知道具体的答案是什么。这些答案也不是一成不变的， 因为这些都是移民局政策或者操作习惯的范畴， 都没有法律依据， 移民局可以这样做，也可以那样做。
目前来说 这几个问题的答案是这样的。
1 可以带入。 我认为移民局的签证官在处理这种申请的时候不会考虑签证人的前置签证， 而只会考虑你申请的签证。 至于为什么这样，我有一个猜测。据说，在美国炮兵部队的操作中，每当发射火炮时，总有一个士兵站在火炮前方，似乎在执行某种重要任务。然而，随着军事技术的发展，人们发现这个士兵实际上并没有明确的作用，但仍然按照传统站在那里。有人深入研究后发现，这一传统可以追溯到更早的时期。当时，炮兵使用的是马拉的火炮，前面站的士兵的任务是拉住马匹，以防发射火炮时马匹受惊逃跑。然而，随着技术的进步，现代炮兵已经不再使用马匹，但这个“前面站一个人”的传统却被保留下来了。
同样申请143/864的时候，都是通过103 转过来的，早期的政策是鼓励大家把103转成143或者864，当时政府给这种转签证的人给予时间上的折算。 但是随着143的签证时间越来越长，目前的审理速度已经超过12年。 那么就出现了一批需要从143申请转864申请的申请人，而移民局还是按照早期的政策继续处理这类申请，也就造成了143转864也可以得到时间的折算。但是仔细想想，这种给143转864时间上折算是不符合原来103转864的政府的初衷的。
2 可以申请豁免，但是需要分别区分 8503 还是 8534. 如果是8503就可以直接递交签证，如果是8534 就需要在申请签证的时候手动申请豁免。
3.2.10. No further application conditions – waiver provisions
Subsection 46(1A) of the Act has the effect that a visa application is invalid if the applicant is in Australia and is subject to a “no further application” visa condition, unless that condition has been waived. Under subsection 41(2A) of the Act, subregulation 2.05(4AA) and 2.05(5A) enable conditions 8503 and 8534 to be waived if the person has a genuine intention to apply for a SESR visa, and in the case of condition 8534, have completed the course of study for which the visa this condition was attached to, was granted. The effect of visa condition 8503 is that the holder will not, after entering Australia, be entitled to be granted a substantive visa, other than a protection visa, while the holder remains in Australia. The effect of visa condition 8534, which is attached to certain student visas, is that a person subject to the condition cannot apply for a visa other than a protection visa, a Subclass 485 (Temporary Graduate) visa or a Subclass 590 (Student Guardian) visa after entering Australia.
If an onshore applicant is subject to an 8503 condition, the Department’s systems are authorised under s495A to waive the condition automatically to enable lodgement of the SESR application.
If an onshore applicant is subject to an 8534 condition, the Department’s systems will allow lodgement of a SESR visa application even though the waiver is not automatically granted in every case. The department’s policy is that the request for a waiver is included with the SESR visa application and, a waiver will be granted if the applicant has completed the course for which the visa with the 8534 condition attached was granted. Decision makers should check that the course was completed and then record the approval of the waiver, and grant the appropriate bridging visa. If the applicant has not completed the relevant course, the SESR visa application should be recorded as invalid and procedures initiated to repay the VAC.
