Don't understand -- 回複:我該怎麽找他?
If "孩子是要我來帶的", then you have "孩子的撫養權", no matter what, right?
Not really know about this legally, but: I think you can wait till your kid coming to the US and united with you. Then, file a custody case in US based on your ex- "deserted" the kid, as he is not living with you?
