October 16, 2026 · By PATH Cross-Border Advisory
A person who had lived and worked in the United States for decades visited Korea after a long absence.
An unexpected diagnosis of terminal cancer followed a health screening during the visit. After deciding to continue treatment in Korea rather than return after a short stay, the client asked PATH whether U.S. Social Security benefits could be claimed early.
Because the client had not yet reached full retirement age, one program to consider was Social Security Disability Insurance, or SSDI.
“Waiting for a decision might itself give me hope.”
During the consultation, we discussed both eligibility and the practical issue of timing. Work history and medical records must be reviewed and the application assessed. Even after approval, a separate waiting period may apply before payments begin.
We asked whether the client wished to proceed despite the time the process could take.
The client explained that waiting for a decision could provide a sense of hope and might help them continue treatment.
Those words stayed with us.
Being told that life expectancy is short does not allow an adviser to decide uniformly what applying means to a person. When the course of treatment and the time ahead remain uncertain, the individual's wishes also matter in deciding whether to apply after understanding the program and its timeline.
SSDI Is Different from Early Retirement Benefits
SSDI (Social Security Disability Insurance) is a benefit to consider when a person insured through work covered by U.S. Social Security can no longer engage in substantial gainful activity because of an illness or disability.
It is separate from early retirement benefits available from age 62. It is also not a means-tested assistance payment based on low income or limited assets.
You may apply for SSDI before full retirement age if you meet the work, insured-status and disability requirements.
An assessment may consider not only cancer itself but also treatment effects that make continued work difficult. The disability must have lasted or be expected to last at least 12 months, or be expected to result in death. You do not necessarily need to wait 12 months before applying.
SSA Disability Eligibility Guide
Terminal Cancer May Qualify for Expedited Review
Certain severe cancers may qualify under the SSA's Compassionate Allowances (CAL) program. The Terminal Illness (TERI) procedure also prioritizes cases involving terminal illness.
However, a description of terminal cancer alone does not satisfy every requirement. Medical evidence of the type and status of the cancer is needed, and insured status based on the person's U.S. work record must also be checked.
Expedited review is intended to accelerate a decision; it does not guarantee approval or immediate payment.

Should You Give Up Applying Because Time May Be Short?
SSDI generally has a five-month waiting period based on the established onset date of disability. Priority processing for terminal cancer does not automatically eliminate this period.
The important point is that the waiting period is not simply counted from the application or approval date. When payments may begin depends on the date the SSA recognizes as the onset of disability and how much time has passed since then.
Rather than concluding that applying has no value solely because of life expectancy, it is necessary to consider the disability onset date, insured status and the burden of preparing records together.
If the individual understands these points and still wishes to apply, starting the process while confirming eligibility may be an option.

Recent Visitors to Korea May Also Consider Applying Online
A U.S. citizen is not excluded from applying for SSDI simply because they are staying in Korea and receiving treatment there.
Someone who worked in the United States until recently and then visited Korea may prepare an application by reviewing their U.S. work history, existing medical records and diagnostic and treatment records from Korea together.
If the online application and identity-verification requirements are met, submitting an initial application online may be considered as a way to start the process. However, recent arrival in Korea or applying online does not itself make the review faster. Additional medical records or confirmation by the responsible agency may still be required after submission.
The person's actual stay or residence in Korea must be reported accurately, and eligibility for expedited review of a serious illness should be checked separately.

Considering Both Eligibility and the Meaning of Applying
After an unexpected cancer diagnosis, many decisions must be made about treatment, daily life and family care. Someone who worked in the United States for many years may also wonder whether they can use the social insurance system into which they paid.
Eligibility, possible payment timing and required records must be explained realistically. At the same time, it is necessary to respect the meaning the individual attaches to the application process after hearing that explanation.
This consultation reminded us that the value of applying for benefits cannot always be judged by cost and time alone.
