请问8老师:
1，父亲为孩子递交F2B的130被批准后，孩子离境回国，还需要通知移民局或者需要填什么表格吗？
-Do you indicate that your child will apply for the immigrant visa in China in the Form I-130 when filed it? If yes, you don't need to do anything, and just wait for National Visa Center to contact you in the future. If no, then you need to file I-824 to request USCIS send your approved I-130 to NVC for process for your child to apply for immigrant visa in China.
2，父亲如果入籍，入籍后怎么update？
-Send a letter to USCIS with the copy of US citizenship certificate to request USCIS to upgrade it from F2B to F1 category.
