In general, if you are a U.S. citizen and your spouse is a conditional permanent resident (CPR), the divorce may result in your spouse losing her conditional status and having to leave the United States. However, there are some exceptions to this rule. For example, if you can show that the marriage was entered into in good faith and not for the purpose of obtaining an immigration benefit, your spouse may be able to apply for a waiver of the joint filing requirement and remain in the United States.
It is important to note that the specific laws and regulations governing divorce and immigration are constantly changing. Therefore, it is essential to consult with an experienced immigration attorney to discuss the specific circumstances of your case.
