Yes, an I-485 can potentially be approved even if the I-130 was approved and the couple separated after the I-130 was filed, especially if the marriage was initially entered into in good faith. However, the separation, particularly if it occurred after the I-130 was filed, will be scrutinized to determine if the marriage was fraudulent at its inception. If the marriage was genuine at the time of the I-130 filing, the separation doesn't automatically disqualify the I-485 application. Additionally, if the couple has a child together, that child can also be included in the I-485 application, provided the child was born within the valid marriage.
