I have 3 more children in Philippines. I declared the 2 and their visa is already on process. I wasn't able to declare my eldest. The reason is I had her when I was 17 and my parents put her under their name so she appeared to be my sister on her birth cert. But now my mom passed away and I am willing to process her papers to be transferred under my name and to undergo dna. will I be able to justify this to the immigration? like I didn't declare her the time I applied becoz I can not prove it on my papers. I based everything from the documents that I can present them. Like if I did declare her as my daughter before and the immigration asks for proof like birth cert, I have nothing to present them. Please give me an advice. Thank you so much!
