International Adoption Process Step by Step: Requirements and Timeline

International adoption involves two parallel legal systems—the U.S. federal immigration process and the sending country's domestic adoption process—running simultaneously. Neither can proceed without the other, and understanding how they interact is the foundation of navigating the process without costly delays. Here is the complete process from beginning to end, with realistic timelines based on active programs in 2025.

Step 1: Determine Your Eligibility

Before selecting a country or agency, confirm you meet basic requirements on the U.S. side:

U.S. citizenship: At least one prospective adoptive parent must be a U.S. citizen.

Age: For an unmarried applicant, USCIS requires at least age 24 when filing Form I-800A and at least age 25 when filing Form I-800. Married applicants file under the applicable joint-applicant rules.

Home study: The household participates in a home study conducted by a qualified provider under the applicable country and agency requirements. The home study evaluates your background, finances, health, relationships, and readiness to parent an adopted child.

Background checks: All household members aged 18+ are fingerprinted for FBI background checks. Disqualifying offenses include felony convictions for child abuse, child neglect, sexual abuse, child pornography, or murder. Other offenses are evaluated on a case-by-case basis.

Individual country programs add their own requirements on top of U.S. requirements. These vary and include restrictions on marital status, age gaps, number of existing children, sexual orientation, and health conditions.

Step 2: Select Country and Agency

These two decisions must be made together. The agency you choose must have:

1. Current Hague accreditation for Hague cases (verify through the CEAS directory at ceadoption.org/aspdirectory)
2. For almost all non-Hague cases, a Hague-accredited primary-provider role under the Universal Accreditation Act, plus current country participation and authorization where required

Not all agencies have programs in all countries. An agency with a strong Colombia program is not automatically equipped to manage an India adoption. Ask any agency how many adoptions they completed in your target country in the last 3 years.

Step 3: Home Study

The home study is a formal assessment conducted by a qualified provider over multiple sessions. It typically includes:

• Individual interviews with each prospective parent
• Joint couple interview
• Interview with all household members including children
• Physical inspection of your home
• Criminal background check results review
• Medical examinations (by your physician; results submitted to the home study agency)
• Financial review
• Reference letters as required by the provider and country

A home study meeting 22 CFR Part 96 standards—which is required for Hague adoption—must cover specific topics including your motivation to adopt, prior experience with children, support network, parenting philosophy, and preparation for adoption-specific challenges like trauma and attachment.

Timeline: Confirm the current completion timeline with the home-study provider.

Cost: Confirm the current provider quote and whether the fee is included in the agency's overall fee.

Step 4: File I-800A with USCIS

The I-800A (Application for Determination of Suitability to Adopt a Child from a Convention Country) is the federal government's determination that your family is qualified to adopt internationally. You file this with USCIS along with:

• Completed home study
• Fingerprint appointment results (scheduled separately at a USCIS Application Support Center)
• Current filing fee under USCIS instructions
• Biographical information for all applicants

Processing time: Check current USCIS processing information; your agency will track the case.

Validity: The I-800A approval period is generally 15 months from USCIS notification of the fingerprint-record results. Check the approval notice and current USCIS instructions for extension rules before it expires.

Step 5: Compile and Submit the Dossier

While waiting for I-800A approval (or after), compile the dossier your sending country requires. A dossier is a package of certified, apostilled documents that the foreign Central Authority uses to verify your eligibility and readiness:

Typical dossier contents:

• Home study (usually in full)
• I-800A approval notice
• Birth certificates for all applicants
• Marriage certificate (if applicable)
• Divorce decrees (if applicable)
• Financial statements (tax returns, bank statements, employment verification)
• Medical examination certificates
• Police/criminal clearance certificates
• Reference letters
• Photographs of family and home

Apostillation: Most documents require an apostille—a form of authentication that certifies a document is genuine. U.S. documents are apostilled by the Secretary of State's office in the issuing state, or by the U.S. Department of State for federal documents.

Translation: Documents that the sending country requires in its official language must be translated by a certified translator.

Dossier expiration: Some documents have expiration dates (police clearances, medical certificates). In programs with long waits, documents expire and must be re-issued. Your agency will track this.

Timeline: Dossier timing varies by country, provider, and document requirements. Submit according to the current agency and country instructions once the required approvals and documents are ready.

Step 6: Wait for Registration and Referral

After dossier submission, the foreign Central Authority registers your family in their adoption system. You are then in a waiting pool for a referral—a specific child matched to your family.

Realistic wait times by program:

• India: approximately 3–4 years from dossier submission to bringing a child home
• Colombia: 12–24 months for some older-child or sibling-group referrals; 3+ years is possible for younger children without special needs
• Bulgaria: approximately 2–4 years from dossier to referral
• Philippines: approximately 2–3 years from dossier submission to referral for non-relative cases

These are program benchmarks with different start and end points. After referral acceptance, the process continues through country-specific court, visa, and travel steps; confirm the current schedule with the agency and country authority.

Step 7: Evaluate and Accept the Referral

When the sending country matches your family with a child, you receive an Article 16 report: a formal document with the child's social, medical, and developmental history. The time to accept or decline is set by the country or agency; follow the notice you receive.

Before accepting: consult an international adoption pediatrician. These are physicians who specialize in evaluating referral files for internationally adopted children. They can interpret medical records, identify common conditions associated with institutional care, assess developmental information, and flag what is absent from the record (which is often as informative as what is present). University of Minnesota, Cincinnati Children's, and Boston Children's Hospital all have established international adoption medicine programs.

Never accept a referral based solely on photographs and your emotional response. The Article 16 report requires expert medical interpretation.

Step 8: File I-800 with USCIS

After accepting the referral, file the I-800 (Petition to Classify Convention Adoptee as an Immediate Relative) with USCIS, attaching the Article 16 report. USCIS verifies the child meets U.S. legal requirements for a "Convention Adoptee."

Critical: In the Hague process, I-800 approval must come before the adoption is legally finalized in the sending country. Do not allow this sequence to be reversed.

Step 9: Article 5/17 Letter and Finalization

After I-800 approval, the U.S. Embassy in the sending country issues an Article 5/17 letter to the foreign Central Authority. This green-lights the adoption for finalization in foreign court.

Travel is typically required for court finalization. Trip requirements vary by program:

• Some countries finalize in one trip of 2–4 weeks
• Bulgaria requires two separate trips 4–6 months apart
• The Philippines requires a 6-month trial custody period in the United States before finalization

Step 10: Immigrant Visa and Homecoming

After foreign court finalization, the child applies for a U.S. immigrant visa at the U.S. Embassy or Consulate:

• IH-3 visa: Adoption fully completed abroad; the child may acquire U.S. citizenship on entry when the applicable statutory criteria are met
• IH-4 visa: Legal custody granted abroad; the family completes the required U.S. adoption and citizenship steps

Realistic Total Timeline

From beginning your home study to your child arriving home: 2.5–5 years for most active programs. India and Colombia at the longer end; Bulgaria potentially faster for families open to significant special needs.

Plan for this timeline from the start. Families who enter international adoption expecting 12–18 months consistently experience shock and frustration—and make worse decisions under that pressure.
