I am Dr. Olivia Bennett, a medical writer and fertility consultant specializing in assisted reproductive medicine. Over the past decade, I have helped more than 300 Chinese families complete their US surrogacy journeys. I wrote this guide for intended parents who are planning US surrogacy but are troubled by the question, “How long will it actually take?” Whether you are just beginning your research or have already entered the matching stage, this timeline can help you establish clear expectations.
Key takeaway: Assuming everything proceeds smoothly, US surrogacy takes approximately 12 to 15 months from formal initiation to the baby’s birth—but if you already have a transferable embryo and matching is efficient, transfer and the start of pregnancy may be completed in as little as 10-11 months. Below, I break down each key milestone by stage.
What Is a US Surrogacy Timeline? (Quick Definition)
A US surrogacy timeline refers to the total time required for every key stage, from the point at which intended parents decide to pursue family building through surrogacy to the moment they take their baby home and complete all legal documentation. It covers six major components: gestational carrier matching, medical screening, legal contracts, embryo transfer, pregnancy monitoring, delivery, and documentation. For intended parents from China, the timeline also involves travel arrangements to the United States, documents for bringing the baby home—such as a Chinese Travel Document—and coordination across international legal systems. Understanding this timeline is essential for budgeting, arranging work, and planning travel to the United States.
Overview of the Five Major Stages of Surrogacy
Stage 1: Initial Preparation and Matching
Submit personal information forms, passports, and medical records, then complete a feasibility assessment. Next comes two-way matching—reviewing gestational carrier profiles, communicating by video, and confirming mutual interest. RSMC's Physician Plus program can provide pre-screened profiles within 14 days.
Stage 2: Screening and Legal Procedures
Approximately 2–3 months. The gestational carrier undergoes medical screening, psychological evaluation, and insurance review. Intended parents and the carrier each have separate attorneys review the surrogacy agreement. An escrow account is established for financial security.
Stage 3: Medical Preparation and Transfer
Approximately 1–2 months. The gestational carrier begins 4–5 weeks of medication for endometrial preparation. The fertility clinic schedules the embryo transfer. RSMC’s in-house lab supports culture through day 7.5 blastocysts with PGT-A genetic screening.
Stage 4: Pregnancy Monitoring
Approximately 8.5 months. HCG tests are performed 10-12 days after transfer, followed by a fetal heartbeat ultrasound at 4–5 weeks. Care transitions to an obstetrician after week 12. Attorneys prepare the Pre-birth Order (PBO) during this time.
Stage 5: Delivery and Documentation
Approximately 1–2 months. Parents travel to the US for delivery. Post-birth, they apply for the birth certificate, US passport, SSN, and Chinese Travel Document. Final escrow reconciliation occurs about three months after birth.
Quick Answer (Start With These Steps)
Here are the fastest paths in the two most common scenarios:
Scenario A: You Already Have a Transferable Embryo
- Start matching immediately—RSMC Physician Plus priority service provides profiles within 14 days
- Legal contract and escrow account (2–3 months)
- Transfer after 4–5 weeks of medication
- Pregnancy (8.5 months) → Delivery → Documentation (1–2 months)
- Total: approximately 11–14 months
Scenario B: You Need to Create Embryos From the Beginning
- Ovarian stimulation and egg retrieval (2–3 weeks)
- Embryo culture and PGT-A testing (3–4 weeks)
- Enter matching and transfer process described in Scenario A
- Total: approximately 14–18 months
Step-by-Step Guide: The Entire US Surrogacy Process
Step 1: Consultation and Initial Assessment
Complete the RSMC online consultation. A fertility consultant will arrange a remote video call with a US physician to provide a feasibility assessment and preliminary timeline estimate based on your medical background.
✅ Sign of success: Receive a physician-signed feasibility assessment.
Step 2: Gestational Carrier Matching
Access RSMC’s in-house database. Screen candidates by age, childbirth experience, and location. Confirm mutual interest through video calls. RSMC’s Physician Plus channel significantly reduces wait times by providing pre-screened candidates.
✅ Sign of success: Both parties sign the matching confirmation.
Step 3: Medical Screening and Legal Contracts
The carrier completes medical and psychological testing. Simultaneously, independent attorneys for both parties draft the surrogacy agreement. An escrow account is funded to manage all payments securely. This stage takes 2–3 months.
✅ Sign of success: Legal clearance issued and escrow funded.
Step 4: Embryo Transfer and Pregnancy Testing
The carrier undergoes 4–5 weeks of medication. The physician performs the transfer. HCG blood tests occur 10 and 12 days later. An ultrasound at 4–5 weeks confirms fetal cardiac activity.
✅ Sign of success: Fetal heartbeat confirmed by ultrasound.
Step 5: Pregnancy Monitoring and Parentage Order
Monitoring continues at the fertility clinic until week 12, then transitions to an OB-GYN. Attorneys file for the Pre-birth Order (PBO) to ensure parents' names are on the birth certificate immediately.
✅ Sign of success: PBO approved by the court.
Step 6: Delivery and Documentation
Parents travel to the US for the birth. Documentation (Birth Certificate, US Passport, SSN, Chinese Travel Document) takes 4–8 weeks. RSMC’s bilingual team assists with all paperwork for a smooth return home.
✅ Sign of success: All documents complete and boarding the flight home.
