Anyone, including an angry spouse, could report you to the Immigration and Naturalization Service (INS) at any time. It is not, however, an automatic step in the court process to make such a report. This does not mean, of course, that it could never happen. But you need not be afraid that the INS will be notified automatically if you file for a restraining order.
You also should be aware of a special provision in the laws governing immigration and naturalization that may apply to you. If your immigration status is dependent on your spouse and you are a victim of domestic violence, you may be able to "self-petition" for legal status under the federal Violence Against Women Act.
