Bringing Korean Parents to the U.S. by a Citizen Child — Preparations to Be Made in a Timely Manner and Without Delay
A significant portion of the calls we receive at the office from Korean citizens is about a recurring question: “My mother has become much weaker since last year. I think it's time for me to take care of her, but where should I start?” This is not a question that can be answered with simple document guidance.
Bringing Korean parents to the U.S. as permanent residents by a U.S. citizen child doesn't end with just the USCIS petition schedule. Parents' health, Korean home and pension, a 5-year gap in U.S. health insurance, family's financial responsibility, and the new daily life of seniors starting anew in the U.S. are all placed on one page together. In today's column, we will go over eligibility for petition, I-864 affidavit of support, PRWORA's 5-year welfare restriction, Medicare eligibility at 65, and the lines that need to be marked on the calendar in order.
1. The starting line for parents' petitions — citizenship, age 21, and the non-waiting line
“According to INA §201(b)(2)(A)(i), U.S. citizens” parents are considered immediate relatives, so they are not subject to annual visa limitations.”
A child who can petition for their parents must be a U.S. citizen and at least 21 years old. Lawful Permanent Residents cannot petition for their parents directly. I often see lawful permanent resident children delaying the decision to “become a citizen first and then petition,” while their parents' health and time slip away. The structure that makes it impossible for lawful permanent resident children to petition for their parents is not subject to policy changes, but rather is the basic framework of family categories enshrined in INA §201(b) and §203(a).
Parents fall under the IR-5 category, defined by USCIS as an immediate relative. The first characteristic of immediate relatives is that there is no annual visa limit. Unlike siblings (F4), married children (F3), or unmarried children over 21 (F1) who wait for years within the Visa Bulletin, parents can proceed to the next step immediately after petition approval without needing a visa number.
According to the latest USCIS processing times, direct family I-130s are operating in the 10-15 month range. For parents residing in Korea, the consular processing stage, which involves the NVC and the U.S. Embassy in Seoul, typically takes around 12-18 months. If your parents are in their late 70s to early 80s, it is clear that this 1-2 year period is not merely an administrative wait but a deadline for the entire family's decision.
2. The I-864 Affidavit of Support and the Poverty Line: 125%—a Different Number
“The income threshold for Form I-864 is 125% of the poverty line published annually by the U.S. Department of Health and Human Services (HHS), and this affidavit is a legally binding contract under INA §213A.”
Even if a parent's petition is approved, a green card is not automatically issued. A U.S. citizen child must submit an I-864 Affidavit of Support. The I-864 is not merely a form, but a legally binding contract under INA §213A. If the parent receives certain public benefits within a specified period, the government can seek reimbursement from the sponsor. The obligation continues until the parent becomes a U.S. citizen, completes 40 quarters of work, permanently departs the U.S., or dies.
Based on the guidelines effective as of March 1, 2026, the adjusted income thresholds for the 48 contiguous states and Washington, D.C., are approximately $27,050 for a two-person household, $34,150 for a three-person household, and $41,250 for a four-person household. A U.S. citizen child’s pre-tax household income must exceed these thresholds to qualify for a sole guarantor.
In practice, a case is divided into two scenarios. If the child's income is sufficient, it is handled with a solo I-864 from the child. If the child's income is insufficient, options include combining household income with an I-864A from a cohabiting family member, or having a U.S. citizen or lawful permanent resident relative submit a separate I-864 as a joint sponsor. Assets can also be used as a supplement, but for parent petitions, 5 times the insufficient amount in available assets must be proven (the 3x standard only applies to citizen spouses and minor children). It should also be noted that the household size and the poverty guideline threshold change depending on whether both parents are sponsored simultaneously or one parent is sponsored first.
3. PRWORA's Five-Year Shadow and the Relief of an Emergency Room Bed
“The Personal Responsibility and Work Opportunity Act of 1996 (PRWORA, 8 USC §1613) imposes a 5-year limit on eligibility for federal means-tested public benefits for ‘qualified aliens.”
From the day your parents arrive in the U.S. after receiving their green cards, two invisible expiration dates begin to run. One is the 5-year mark when a lawful permanent resident becomes eligible to apply for U.S. citizenship. The other is the 5-year restriction on eligibility for federal means-tested public benefits for a ‘qualified alien" imposed by PRWORA. The latter is the expiration date that naturalized citizen children are most likely to miss.
For five years, parents are generally ineligible for federally means-tested welfare programs like SSI (Supplemental Security Income), non-emergency Medicaid, SNAP (food stamps), and TANF. While there are separate exemption categories for individuals like refugees/asylees or those with military service, parents arriving with permanent residency from South Korea do not qualify for these exemptions. Some states offer programs similar to SNAP and Medicaid for those with less than five years of permanent residency, funded by their own state resources. The safety net available will differ depending on whether the parents reside in New York/New Jersey or Texas/Florida.
Fortunately, there's emergency medical care. Emergency Medicaid works regardless of the 5-year limitation, provided it's an emergency medical condition. This includes emergency room care, labor and delivery, and life-threatening hospitalizations. However, chronic disease management, outpatient prescriptions, and routine check-ups are not considered emergency medical care. The OBBBA (One Big Beautiful Bill Act) in 2026 will reduce some Medicaid eligibility categories, but non-emergency Medicaid eligibility will remain available after the 5-year ban for parents with permanent resident status. However, the federal matching rate for the ACA expansion of Emergency Medicaid (FMAP) will decrease, potentially leading to different state burdens, so it's best to reconfirm at the time of implementation.
4. Medicare: How to Survive the Five Years Between 60 and 65
“Medicare Part A is available without a premium to individuals age 65 and older who have paid Social Security taxes for approximately 10 years (40 quarters), or whose spouse has paid these taxes.”
When parents in their 70s arrive with their green cards, the first word they encounter within the U.S. healthcare system is ‘Medicare'. Eligibility for Medicare has two main paths. If you or your spouse has paid Social Security taxes for approximately 10 years (40 quarters) and reached age 65, you automatically qualify for Part A without any premium. If you have no U.S. work history, you must complete five consecutive years of residency after obtaining permanent residency to be eligible for Part A with a premium, and you can enroll in Part B concurrently. Parents from Korea who first entered the U.S. as permanent residents in their 60s or 70s virtually fall onto the second path.
The main agenda item for the family meeting is how to fill this five-year healthcare coverage gap. Options include including parents as dependents on a U.S. citizen child's family health insurance plan, ACA Marketplace plans, and separate private senior insurance. While it has been reported that ACA subsidy eligibility will be narrowed by OBBBA in 2025, the subsidy will be limited to certain categories such as legal permanent residents, Cuban/Haitian entrants, and those from COFA starting January 2027. However, parents with legal permanent resident status will remain within this scope. Policy changes will need to be reconfirmed at the time of enrollment.
You also need to organize your safety net in Korea. Korean National Health Insurance is suspended for long-term overseas stays, and the six-month residency requirement in Korea has been strengthened since the amendment in April 2024. The Korea-U.S. Social Security Agreement (effective April 1, 2001) guarantees the sum of coverage periods and exemption from double taxation, allowing you to combine your Korean National Pension coverage with your U.S. SSA coverage to qualify for old-age pensions in both countries. The lump-sum refund (NPS lump sum) is handled separately from the agreement under Korean National Pension law, and the claim deadline is the date of overseas relocation notification, not the date of permanent residency issuance. If you do not claim within five years of notification, the statute of limitations will expire.
Closing remarks
There is one more point to clarify. Even if parents obtain their green cards and then U.S. citizenship after five years, they cannot sponsor other children in the U.S. from their siblings, meaning aunts and uncles remaining in Korea. The authority to sponsor siblings (F4) rests with the U.S. citizen child directly. As of the May 2026 Visa Bulletin, the priority date for F4 applications from Korea remains September 15, 2008. Even if you apply now, you will face a waiting period of approximately 17 to 18 years. This is why it is commonly agreed upon within families to “bring the parents over quickly, and then sponsor siblings later.”.
There is no set timetable for bringing your parents over. However, there are clear items that must be included in the timetable. These are: verifying your children's citizenship, checking the validity period of your parents' Korean passports, calculating the I-864 income threshold and household size, determining in advance if a joint sponsor is needed, organizing your parents' chronic illness prescriptions and Korean medical records in English, and noting in your calendar any changes to your parents' housing, pension, and health insurance eligibility in Korea.
When two five-year deadlines, the age-65 Medicare eligibility threshold, the 1,251 TP3T poverty line figure, and the 17–18-year F4 waiting period all appear on a single page, families can still find their way. The first practical steps can be summarized in three points. First, verify whether the child has obtained citizenship and meets the age-21 requirement, and schedule the I-130 application process. Second, calculate the I-864 income threshold based on the number of people in your household and, if it falls short, identify potential joint sponsors in advance. Third, review health insurance options in advance to bridge the five-year gap in Medicare coverage. These three items are the first entries on the parent petition calendar.
