相信很多人在担保他们父母的同时，如果弟弟妹妹还很小或者还在读书，一般都会考虑把弟弟妹妹也担保过来加拿大。然而随着父母团聚处理时间越来越长，往往递担保的时候弟弟妹妹还不够22周岁，可是在等待的过程中因为时间太长，弟弟妹妹已经超过22周岁了。
这种情况网上基本有两种说法：
第一种，递担保到CPC-M的时候，如果Dependent Children还不够22周岁及未婚，就是锁定了Option A。
第二种，即使递担保的时候还不够22周岁，如果审理过程中超过了22周岁，就要一直保持全日制高等教育、经济依赖父母、未婚。
“Your child or a child of your spouse or common-law partner will be considered a dependent child if that child
A.is under the age of 22 and not married or in a common-law relationship; or
B.married or entered into a common-law relationship before the age 22 and, since becoming a spouse or a common-law partner, has
been continuously enrolled and in attendance as full-time students in a post secondary institution accredited by the relevant government authority and
depended substantially on the financial support of a parent; or
is 22 years of age or older and, since before the age of 22, has
been continuously enrolled and in attendance as full-time students in a post secondary institution accredited by the relevant government authority and
depended substantially on the financial support of a parent; or
C.is 22 years of age or older, has depended substantially on the financial support of a parent since before the age of 22 and is unable to provide for him/herself due to a medical condition. ”
最近我在南亚和东南亚的英语移民论坛找到一个链接到CIC的文件“OP 2 Processing Members of the Family Class”。链接为http://www.cic.gc.ca/English/resources/manuals/op/op02-eng.pdf
其中在第18页5.23. When must requirements be met by family members?.找到这个问题的答案。
“Dependent children under 22 years of age
Is under 22 years of age and not a spouse or common-law partner when the application is received by CPC-M; and
without taking into account their age, they continue not to be married or not involved in a common-law relationship at visa issuance and when they enter Canada.”
意思是说，递交到CPC-M的时候如果随行子女未超过22周岁，那他（她）的年龄将维持在未超过22周岁，即使签证或登陆时已经超过22周岁(还是要保持未婚)。
而那些递交担保时已超过22周岁的，一定要保持全日制高等教育、经济依赖父母、未婚，直到登陆加拿大。
这是2006.11.14的文件，我在CIC搜索了一下，没有找到日期比它更新而同是Processing Members of the Family Class的文件，所以我觉得这文件应该已经是最新的了。
当然，我的英语有限，可能有些地方理解错误，有的话希望大家指出来。
P.S.不知道这些适不适用于投资移民的随行子女，不过相信CIC对dependent children只有同一套标准。
最后祝各位，无论是学习、工作、探亲还是移民，无论是技术移民、团聚移民、投资移民还是其它类移民，早日拿到签证！http://forum.iask.ca/editor/images/smilies/default/13.gif
