A divorce in Montana can affect a noncitizen spouse's immigration status and a sponsoring spouse's financial obligations, but the Montana court does not decide either one. Those questions belong to federal immigration law. This page gives an outline so you know what to ask, and it is not a substitute for an immigration lawyer. A&M Law practices family law and does not practice immigration law. This page is part of our Montana Divorce Guide.
Filing for Divorce Does Not Depend on Status
To get a dissolution of marriage (the statutory term for divorce) in Montana, one spouse must have been domiciled in the state, or stationed here in the armed services, for 90 days before filing, and the marriage must be irretrievably broken (MCA § 40-4-104(1)). The statute says nothing about citizenship or immigration status, and a marriage performed in another country is ended the same way as one performed here. Whether a particular person is domiciled in Montana can be a fact question. See the residency requirement for divorce.
Conditional Residence Based on Marriage
Under federal law, a person who obtains permanent resident status as the spouse of a U.S. citizen or permanent resident, by virtue of a marriage entered into less than 24 months before obtaining that status, receives it on a conditional basis (8 U.S.C. § 1186a(a)(1), (h)(1)). To remove the conditions, the conditional resident and the petitioning spouse must jointly submit a petition during the 90-day period before the second anniversary of obtaining status and appear for an interview (§ 1186a(c)(1), (d)(2)). The petition states, among other things, that the marriage was lawful where it took place, "has not been judicially annulled or terminated, other than through the death of a spouse," and was not entered into to obtain admission as an immigrant (§ 1186a(d)(1)).
If no petition is filed, the statute directs that permanent resident status be terminated as of the second anniversary (§ 1186a(c)(2)). A divorce makes the joint petition unavailable, which is where the waiver comes in.
The Waiver of the Joint Filing Requirement
The Secretary of Homeland Security may, as a matter of discretion, remove the conditions for a person who cannot meet the joint petition requirements if the person demonstrates one of several things (8 U.S.C. § 1186a(c)(4)). One is that "the qualifying marriage was entered into in good faith by the alien spouse, but the qualifying marriage has been terminated (other than through the death of the spouse)" and the person was not at fault in failing to meet the requirements. Others cover extreme hardship and a spouse or child who was battered or subjected to extreme cruelty.
USCIS explains that a conditional resident may request a waiver before or after the 90-day period, and that if a person is still in pending divorce proceedings and has filed a waiver request, it will ask for a copy of the final decree. The evidence that matters is evidence that the marriage was real: shared residence, finances, and life together. What you say in the Montana case about when and why the marriage ended should be accurate, because the same facts may be reviewed by immigration officers.
The Federal Rules at a Glance
| Topic | Rule in outline | Source |
|---|---|---|
| Conditional residence | Applies when permanent residence was obtained through a marriage entered into less than 24 months earlier | 8 U.S.C. § 1186a(a)(1), (h)(1) |
| Joint petition to remove conditions | Filed by both spouses during the 90-day period before the second anniversary of obtaining residence | 8 U.S.C. § 1186a(c)(1), (d)(2) |
| Waiver when the marriage has ended | Discretionary; the marriage was entered into in good faith but has been terminated, and the applicant was not at fault in failing to meet the joint filing requirements | 8 U.S.C. § 1186a(c)(4)(B) |
| Waiver for abuse | Discretionary; good faith marriage, and the spouse or child was battered or subjected to extreme cruelty | 8 U.S.C. § 1186a(c)(4)(C) |
| Affidavit of support | Sponsor agrees to maintain the sponsored person at not less than 125 percent of the federal poverty line; divorce does not end it | 8 U.S.C. § 1183a(a); uscis.gov |
Affidavit of Support Obligations Survive Divorce
A person who sponsors a family member for permanent residence signs an affidavit of support. By statute it is a contract in which the sponsor agrees to provide support to maintain the sponsored person at an annual income of not less than 125 percent of the federal poverty line, and it is legally enforceable against the sponsor by the sponsored person and by government agencies that provide means-tested public benefits (8 U.S.C. § 1183a(a)(1)).
USCIS states plainly: "Divorce does not end the sponsorship obligation." The obligation generally continues until the sponsored person becomes a U.S. citizen or is credited with 40 quarters of work, and it ends if the sponsor or the sponsored person dies or if the sponsored person stops being a lawful permanent resident and leaves the United States.
This federal obligation is separate from Montana maintenance, which has its own test under MCA § 40-4-203 and is decided by the divorce court. How the two interact in a particular case, and whether a settlement should address the affidavit, are questions to take up with both a family lawyer and an immigration lawyer. For the state side, see spousal maintenance in Montana.
Naturalization Timing
The shorter residence period for naturalization available to the spouse of a U.S. citizen requires that the applicant have been "living in marital union with the citizen spouse" during the three years before applying, with an exception for a person who was battered or subjected to extreme cruelty (8 U.S.C. § 1430(a)). A separation or divorce can therefore change which path to citizenship is open and when. Ask an immigration lawyer before you file either a divorce petition or a naturalization application.
Parenting, Safety, and Getting the Right Help
Montana decides a parenting plan by the child's best interest, and the listed factors in MCA § 40-4-212(1) do not include a parent's citizenship or immigration status. Practical issues such as international travel with a child and passports should be written into the plan. See parenting plans in Montana.
Federal law provides waivers and protections for spouses who have been abused, so no one should stay in a dangerous marriage out of fear for their status. If you are in danger, call 911. The National Domestic Violence Hotline is 1-800-799-7233. Our page on divorce and domestic violence covers the protective orders Montana courts can issue, and the eligibility statute, MCA § 40-15-102, does not make protection depend on immigration status.
The safest sequence is to talk to an immigration lawyer first, then set the timing of the divorce with both lawyers informed. If you and your spouse are on good terms, an agreed process such as an uncontested divorce can make it easier to coordinate dates and documents.
