求教，给岳父岳母申请LTVP

男， 公民，男父母没有办法来新，女LTVP , 怀孕ing，宝宝出生后， 想给岳父岳母申请LTVP ，打电话去ICA,接线员说要提前写信给ICA 批准，才可以申请。。。 可是得到的ICA 回复如下：
There no parents in law scheme.Kindly note that for Parents Scheme, only biological or adopted child (with documentary proof) may sponsor the applicant.For more information on Long Term Visit Pass (Parent Scheme), please visit our webpage for Visitor whose Child (above 21 years old) is a Singapore Citizen (SC) or Singapore Permanent Resident (SPR).
       所以意思是不可以给岳父岳母申请LTVP ???
求大神指教。。。。
