EB-5 for children under 21: CSPA age protection rules and the green card roadmap

EB-5 for children under 21 is one of the most complex legal issues Vietnamese families need to master when considering theVisa EB-5. Under the Immigration and Nationality Act (INA), a “child” in immigration law is defined as a person who is unmarried and under 21. When an investor’s child turns 21 before receiving a green card, they “age out” — the child is no longer eligible to accompany their parents on the EB-5 petition.

To address this problem, the US Congress passed the Child Status Protection Act (CSPA) in 2002. The Act provides a mathematical formula that “freezes” a child’s age based on the time the I-526E or I-526 petition was pending. However, following the policy update fromU.S. Citizenship and Immigration Services (USCIS)on 08/08/2025, the CSPA mechanism has become less favourable than it was in 2023–2025.

Why CSPA matters for EB-5 children under 21

An EB-5 petition allows the principal investor to bring their spouse and unmarried children under 21 (derivative beneficiaries) to immigrate with them and receive conditional green cards. However, the EB-5 roadmap usually takes 3–7 years overall, and the I-526E adjudication stage alone can take 18–30 months for Unreserved or High Unemployment petitions.

During this long period, children may turn 21 before completing visa issuance or adjustment of status. Before the CSPA, this situation almost ended the chance of accompanying their parents — the child had to apply for a different visa on their own (such as an F-1 student visa, or wait for their parents to sponsor them later as permanent residents). The problem is even more serious for families from countries with long EB-5 backlogs such as China, India and, at certain times, Vietnam.

The CSPA addresses this by allowing the time the I-526E was pending to be subtracted from the child’s biological age at the time the visa “becomes available”. The result is a “CSPA age” that differs from the actual age and can keep the child under 21 in the legal sense.

The CSPA age formula

Under INA 203(h) of the CSPA andUSCIS Policy Manual guidance on the CSPA, a child’s CSPA age in an EB-5 case is calculated using the basic formula:

CSPA age = Biological age when the visa becomes available − Time the I-526E (or I-526) was pending

Where:

• “Biological age when the visa becomes available” is the child’s actual age when the EB-5 immigrant visa becomes available for the case — that is, the date the Priority Date is current in the Visa Bulletin.
• “Time the I-526E was pending” is the number of months from the date USCIS received the I-526E (or I-526) to the date of approval.

If the result is under 21, the child is still considered a “child” under the immigration definition and is eligible to accompany their parents. If the result is 21 or over, the child ages out and cannot accompany their parents on the EB-5 petition.

An important accompanying condition: the child must “seek to acquire” permanent resident status within 1 year of the date the visa becomes available. “Seeking to acquire” is usually understood as filing a DS-260 (for Consular Processing) or an I-485 (for AOS).

The USCIS policy update of 08/08/2025 — its impact on calculating CSPA age

This is the most important change in the last three years to how CSPA age is calculated for EB-5. According tothe official USCIS announcement on the CSPA update, the agency reversed its 2023 policy and returned to the previous rule.

The period from 14/02/2023 to 14/08/2025

During this period, USCIS used the Visa Bulletin’s Dates for Filing chart (Chart B) to determine when a visa becomes available for CSPA age purposes. Because Dates for Filing are usually several months to several years ahead of Final Action Dates, EB-5 families could “lock in” their child’s CSPA age earlier, creating a large safety margin for children close to 21.

During this period, many EB-5 cases from Vietnam, India and China used Dates for Filing to protect their children’s age — especially when using Concurrent Filing of the I-485 with the I-526E.

The period from 15/08/2025 onwards

Under the 08/08/2025 update, USCIS switched to using the Final Action Dates chart (Chart A) for all AOS applications filed from 15/08/2025. This aligns with the approach the US Department of State already applies to Consular Processing.

The practical consequence of the change: CSPA age is “frozen” later than under the 2023 policy, causing many children close to 21 to age out even though they would have qualified under the old policy. In the May 2026 Visa Bulletin, both Reserved and Unreserved (for Vietnam) are current under Final Action Dates, so the impact on Vietnamese cases is negligible — but this could change if retrogression occurs.

Cases pending before 15/08/2025

USCIS has confirmed it will continue to apply the 2023 policy (Dates for Filing) to AOS applications filed before 15/08/2025. This rule protects investors who relied on the old policy when deciding to file.

Three examples of how CSPA is calculated

To understand how CSPA applies, consider three typical scenarios for Vietnamese families.

Scenario 1 — A child under 18 when the I-526E is filed

Family A has a 16-year-old child when filing a Rural TEA I-526E in January 2026. The I-526E is approved after 8 months (September 2026). When the Visa Bulletin is current for the Rural category (assumed September 2026), the child is 16 years and 8 months old. CSPA age = 16 years 8 months − 8 months = 16 years.

Result: the child is still far from the age-21 threshold, with no risk of ageing out. The family can proceed with the consular interview or AOS as normal.

Scenario 2 — A child aged 19 when the I-526E is filed, with the Reserved category current

Family B has a 19-year-old child when filing a High Unemployment I-526E in January 2026. The I-526E is approved after 22 months (November 2027). At approval, the child is 20 years and 10 months old. Because the Reserved category was current continuously from the month of filing to the month of approval, Final Action Dates were current for the whole period.

CSPA age = 20 years 10 months − 22 months = 19 years. Result: the child is still eligible to accompany their parents. However, the family must file a DS-260 or I-485 within 1 year of approval to meet the “seek to acquire” requirement.

Scenario 3 — A child aged 20 at filing, with the Unreserved category in retrogression

Family C has a child aged 20 years and 6 months when filing an Unreserved I-526E in January 2026. The I-526E is approved after 28 months (May 2028). However, the Unreserved category for Vietnam went into retrogression in 2027, and Final Action Dates do not become current until November 2028.

When Final Action Dates become current (November 2028), the child is 23. CSPA age = 23 years − 28 months pending = 20 years 8 months. Result: the child qualifies under the CSPA but must act within 1 year of November 2028. This situation has a very narrow safety margin, with a high risk of ageing out if paperwork is delayed.

Strategies for protecting your child’s age in EB-5 for children under 21

For Vietnamese families with children approaching 21, four practical strategies should be applied together.

Strategy 1 — Choose the Rural TEA category

The Reserved Visa Rural TEA category receives priority processing from USCIS under theEB-5 Reform and Integrity Act 2022 (RIA). Rural I-526E adjudication averages 4–12 months — the shortest of all EB-5 categories. A short pending time means the CSPA age is frozen early, with a large safety margin.

Strategy 2 — Use Concurrent Filing if you are in the United States

If the investor and family are in the United States on valid visas,Concurrent Filing EB-5allows the I-485 to be filed together with the I-526E. Filing the I-485 early usually satisfies the 1-year “seek to acquire” requirement and starts the age-protection process.

Strategy 3 — Prioritise Consular Processing if the I-526E is approved first

For families in Vietnam, once the I-526E is approved, file the DS-260 and complete the consular interview at the US Consulate General in Ho Chi Minh City as soon as possible. Under USCIS policy, the US Department of State always uses Final Action Dates for CSPA purposes in Consular Processing — so this principle has not changed since the August 2025 update.

Strategy 4 — Follow the Visa Bulletin closely

While the petition is pending, the family should check Final Action Date status for the chosen category every month. Any sign of retrogression requires a timely change of strategy, especially for children close to 21.

Common mistakes when applying CSPA to EB-5

According to real-world data from EB-5 immigration lawyers, three common mistakes cause children to lose CSPA benefits.

The first mistake is miscalculating the “biological age when the visa becomes available”. Some families use the I-526E approval date instead of the date Final Action Dates became current for the category — two dates that can be many months apart. Under the 2025 update, the date Final Action Dates become current is the correct reference point.

The second mistake is failing to meet the 1-year “seek to acquire” requirement. Many families wait too long to file the DS-260 or I-485 after the visa becomes available, losing CSPA protection even though the arithmetic qualified.

The third mistake is not accounting for a child marrying during the wait. Under the INA, a “child” must be both under 21 and unmarried. If the child marries before receiving a green card, they automatically lose derivative beneficiary status, regardless of their CSPA age.

Options if your child ages out

In the worst case, where a child ages out and cannot accompany their parents on the EB-5 petition, the family still has three options.

The first option is for the child to continue studying in the United States on an F-1 visa and apply for EB-5 themselves with a separate investment once they have the funds. It is an expensive but independent route.

The second option is for the parents, once they become permanent residents (after the I-829), to sponsor the child in the F2B category (Unmarried Sons and Daughters of Lawful Permanent Residents). However, F2B has a long backlog, usually 5–7 years for Vietnam.

The third option is to wait for the parents to become US citizens (5 years after the conditional green card) and sponsor the child in the F1 category (Unmarried Sons and Daughters of U.S. Citizens). The F1 wait for Vietnam is 7–10 years.

EB-5 for children under 21 requires Vietnamese families to prepare carefully on timing, choice of project category and filing strategy. Especially for families with children aged 17 or older, planning for EB-5 now is a prerequisite for ensuring the whole family can settle in the United States together. Consulting an immigration lawyer experienced in the CSPA and closely following USCIS policy updates are what determine the petition’s success.
