Yes, a single woman can adopt a child in every U.S. state. No federal or state law requires adoptive parents to be married, and all three main paths — domestic infant adoption, foster care adoption, and international adoption — are open to unmarried applicants. What varies is the cost, the wait, and how welcoming a given agency or foreign country is to single-parent households.
Who Qualifies to Adopt
Most states set the minimum age for adoptive parents at 21, though a few allow adoption at 18. For an international adoption through a country that participates in the Hague Adoption Convention, federal regulations require unmarried applicants to be at least 24 and to habitually reside in the United States.1eCFR. 8 CFR 204.307 – Who May File a Form I-800A or Form I-800
Beyond age, the qualifications center on whether you can provide a safe, stable home. You’ll need to show steady income, but you don’t have to be wealthy or own a home. A physical exam within the past 12 months is required. Controlled conditions like high blood pressure or diabetes won’t disqualify you; a serious health problem affecting life expectancy may prompt additional review.2AdoptUSKids. Home Study
Every adult in your household must pass a criminal background check and a child abuse registry screening, and fingerprint-based FBI checks and local police clearances may also be required. Convictions involving violence against children are typically automatic disqualifiers. Other offenses are evaluated case by case.
The Three Paths and What Each One Asks of You
Domestic Infant Adoption
This route usually goes through a licensed private agency or an adoption attorney. Birth parents review family profiles and often choose who will adopt their child, so the process involves writing a profile letter, sharing photos, and sometimes meeting the birth family. Wait times for single applicants vary widely, but domestic infant adoptions generally take one to three years from start to finalization.
The consent revocation period catches many first-time adopters off guard. After a birth parent signs consent, most states give them a window to change their mind, ranging from as little as 72 hours to 30 days or more. A few states make consent irrevocable immediately upon signing. A failed match can also mean lost expenses.
Total costs typically run between $25,000 and $60,000, covering agency fees, legal costs, birth parent expenses where state law permits, and the home study. Attorney-facilitated adoptions fall in a similar range.
Foster Care Adoption
Foster care is the most financially accessible path. Most adoptions from the public foster care system cost little to nothing, and even minimal fees are often reimbursable.3AdoptUSKids. Frequently Asked Questions About Adopting From Foster Care Children available for adoption through foster care are those whose biological parents’ rights have been terminated by a court. Many are older, part of sibling groups, or have special needs.
Single applicants are often well-received in the foster care system, where the need for stable homes outpaces the pool of approved families. Children who meet the “special needs” definition (a broad category that can include older children, children of certain ethnic backgrounds, sibling groups, or children with medical conditions) may qualify for ongoing federal adoption assistance through the Title IV-E program. These monthly subsidies are negotiated individually for each child and can continue until the child turns 18, or beyond in some states.4Child Welfare Policy Manual.

International Adoption
International adoption adds a second layer of legal requirements: you must comply with both U.S. immigration law and the laws of the child’s country of origin.5U.S. Citizenship and Immigration Services. Bringing Your Internationally Adopted Child to the United States The U.S. side begins with filing Form I-800A (for Hague Convention countries) or Form I-600A (for non-Hague countries), which triggers a federal background check and home study review by USCIS.
The bigger hurdle for single women is that the child’s country sets its own rules. Some countries welcome single-parent adoptions; others restrict or prohibit them. China ended its international adoption program in 2024. Russia has long restricted adoptions to citizens of countries that recognize same-sex marriage, which effectively blocks most American applicants regardless of marital status. South Korea and several other nations either prohibit or heavily limit placements with unmarried parents. Check the specific country’s current policy before investing time and money, because these rules change frequently.
The Home Study
Every adoption in the United States requires a completed home study, whether you’re adopting domestically, internationally, or through foster care.2AdoptUSKids. Home Study A licensed social worker conducts the evaluation, and the process typically takes three to six months.
Expect interviews about your personal history, childhood, motivation to adopt, parenting approach, and support network. For single applicants, the questions get pointed but reasonable: how will you handle childcare, emergencies, and the day-to-day of parenting without a partner? The social worker will also visit your home to confirm it’s safe for a child, review income verification like tax returns and pay stubs, and collect three to four non-relative references. Everyone in the household will need a physical exam within the past year and a TB test.2AdoptUSKids. Home Study
The home study isn’t designed to catch you off guard. Social workers are looking for self-awareness, honesty, and genuine readiness. Being single doesn’t count against you. Having no plan for how you’ll manage as a single parent does.
What It Costs and What Help You Can Get
Costs vary enormously by path. Foster care adoption is often free, with most associated fees reimbursable.3AdoptUSKids. Frequently Asked Questions About Adopting From Foster Care Domestic infant adoption through a private agency typically runs $25,000 to $60,000. International adoption sits somewhere in between, with fees varying by country plus mandatory USCIS filing costs and travel expenses.
The federal adoption tax credit helps offset those costs. For adoptions finalized in 2026, the maximum credit is $17,670 per child. You can claim the full credit if your modified adjusted gross income is below $265,080. The credit phases out between $265,080 and $305,079, and disappears above $305,080. For foster care adoptions of children with special needs, you can claim the full credit amount even if your actual expenses were lower.6Internal Revenue Service. Adoption Credit
If your employer offers a qualified adoption assistance program, up to $17,670 of employer-provided reimbursement can be excluded from your taxable income for 2026, subject to the same income phase-out. You can use both the tax credit and the employer exclusion in the same adoption, but not for the same expenses.
Children adopted from foster care who meet the special needs definition may also qualify for monthly Title IV-E adoption assistance payments, Medicaid coverage, and reimbursement of one-time adoption expenses up to $2,000 depending on the state. These benefits are negotiated before finalization and written into the adoption assistance agreement.
Time Off Work After Placement
The Family and Medical Leave Act covers the placement of a child for adoption, entitling you to up to 12 weeks of unpaid, job-protected leave. To qualify, you must have worked for your employer for at least 12 months, logged at least 1,250 hours during the previous year, and work at a location where your employer has at least 50 employees within 75 miles.7U.S. Department of Labor. Fact Sheet #28: The Family and Medical Leave Act Public agencies and schools are covered regardless of size.
Federal government employees get a better deal under the Federal Employee Paid Leave Act: up to 12 weeks of paid parental leave for adoption placement. The leave must be used within 12 months of placement, and the employee must agree in writing to return to work for at least 12 weeks afterward.8U.S. Department of Labor. Paid Parental Leave Many private employers now offer paid adoption leave. Check your benefits handbook, because this is one of the fastest-changing areas of workplace policy.
From Placement to Final Decree
Once you’re matched and placement occurs, the legal process moves through two phases: post-placement supervision and court finalization.
During post-placement, a social worker visits your home at regular intervals, typically over three to twelve months depending on your state and the type of adoption. These visits monitor how the child is adjusting and how the family is integrating. The social worker files reports with the court summarizing what they’ve observed.
Finalization happens at a court hearing where a judge reviews the home study, post-placement reports, background checks, and consent records, then signs the final adoption decree. The hearing itself usually lasts 30 to 60 minutes. Your attorney presents the case, you answer a few questions about your understanding of adoption and your commitment to the child, and the judge signs the order. That decree permanently establishes the legal parent-child relationship, with the same rights and obligations as biological parentage.
Where Single Applicants Hit Friction
Legally, being single is not a barrier. Practically, a few points come up repeatedly. Some private agencies, particularly faith-based ones, may prefer married couples or decline to work with unmarried applicants. Around a dozen states have enacted religious exemption laws allowing certain agencies to make placement decisions based on their religious beliefs, which can affect single applicants indirectly. If one agency turns you down, it doesn’t mean others will. Secular agencies, public foster care systems, and many faith-based agencies welcome single parents.
Birth parents in domestic infant adoption choose who adopts their child, and some prefer two-parent households. That can mean a longer wait, though plenty of birth parents specifically seek out single women they connect with. In international adoption, the restrictions are more concrete: some countries simply won’t place children with unmarried applicants, and that isn’t negotiable.
The most practical challenge has nothing to do with discrimination. It’s the absence of a second income and a second pair of hands. The home study will explore how you plan to handle childcare, emergencies, and the financial demands of parenthood on your own. A strong, documented support network of family, friends, and childcare providers makes a real difference in both the approval process and the reality that follows it.
