I am also considering the time frame in between my 2 year stay and lodging my 887 application. Did you applied 887 for your daughter after getting her passport? or with her birth certificate and updated her passport later.
my baby's due date and my 2 years stay are very close with each other. And getting his passport will take few weeks that i want to skip if i can lodge the application with birth certificate.
BTW - Have you got your PR or still waiting?
