AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Most new Nigerian arrivals get health cover through an employer or the ACA Marketplace. HealthCare.gov says lawfully present immigrants, including green card holders and people on valid non-immigrant visas, can buy Marketplace coverage, but from 1 January 2027 savings (premium tax credits) are limited to lawful permanent residents, Cuban or Haitian entrants and COFA migrants. Medicaid usually starts five years after a green card is issued.
Why cover matters from week one
Medical bills in the US are paid by insurance, by the patient, or by a mix of both. There is no general public system that a new arrival can fall back on in the way many Nigerians expect from experience of the NHS or of paying cash at a private hospital in Lagos. A single emergency admission without insurance can produce a bill that takes years to clear. Arranging cover is therefore one of the first money decisions, alongside your Social Security number and bank account (see the first 90 days checklist).
The three main routes
| Route | Who it suits | Key point |
|---|---|---|
| Employer plan | Anyone with a job that offers benefits | Premiums are usually taken from your paycheck; check when cover starts |
| ACA Marketplace | Lawfully present immigrants without suitable employer cover | Savings limited to certain statuses from 2027 |
| Medicaid / CHIP | Lower-income residents who meet state rules | Generally 5 years after qualified non-citizen status |
Employer cover
If your employer offers a plan, it is often the simplest route, because employers commonly pay part of the premium and your share comes out of each paycheck before or after tax. Ask HR on day one when cover begins, which family members can be added, and what the deductible and out-of-pocket maximum are. Our guide to your first paycheck shows where the premium appears.
The Marketplace
HealthCare.gov says "certain lawfully present immigrants can get Marketplace coverage." Lawfully present includes qualified non-citizens such as green card holders, humanitarian statuses such as TPS, refugees and asylees, and people on valid non-immigrant visas. Some states run their own marketplace website rather than HealthCare.gov; the site will direct you to it.
Outside the annual open enrolment period, you normally need a qualifying life event to enrol. Check on HealthCare.gov, or your state's marketplace, whether your move to the US or a change in status gives you a special enrolment window, and act quickly, as such windows are time-limited.
The 2027 change to savings
Premium tax credits lower the monthly cost of a Marketplace plan. HealthCare.gov says people with income "between 100% and 400% of the FPL" (the federal poverty level) may qualify. It also says that starting on 1 January 2027, savings are limited to lawful permanent residents, Cuban or Haitian entrants and COFA migrants. Other statuses may still buy Marketplace coverage, but not with savings.
| Status | Marketplace coverage | Savings from 2027 |
|---|---|---|
| Green card holder | Yes | Yes, if income and other rules are met |
| H-1B, L-1 or other work visa | Yes, if lawfully present | No |
| F-1 student | Yes, if lawfully present | No |
| Refugee or asylee without a green card | Yes | No |
For a family on an H-1B, this means the 2027 plan year may cost the full premium. Compare the employer plan carefully, even if it seemed expensive before.
Medicaid and the five-year wait
HealthCare.gov says green card holders are generally eligible for Medicaid and CHIP five years after getting qualified non-citizen status, with exceptions for former refugees and asylees, a state option for lawfully residing children and pregnant people, and emergency Medicaid for emergency conditions. During the wait you may still use the Marketplace. Full detail is in Medicaid for Nigerian green card holders.
If a green card case is pending
A Department of Homeland Security public charge rule, effective 18 September 2026, lets officers consider means-tested benefits, and Medicaid is named among them. The groups suing to stop the rule allege it also reaches tax credits; that is their allegation and is not settled. If anyone in your household is applying for a green card, take advice before enrolling in Medicaid or claiming Marketplace savings, and see does using benefits affect a green card application?
Reading a plan: the terms that cost money
- Premium
- What you pay each month to have the plan, whether or not you use it.
- Deductible
- What you pay for covered care each year before the plan starts sharing costs.
- Copay / coinsurance
- Your share of each visit or bill after the deductible.
- Out-of-pocket maximum
- The most you pay for covered care in a year; the plan pays covered costs above it.
- Network
- The doctors and hospitals the plan works with; going outside it can cost far more.
Worked example
Example only. Plan A costs $250 a month with a $6,000 deductible; Plan B costs $400 a month with a $1,500 deductible. Over a year the premiums are $3,000 for A and $4,800 for B, a $1,800 difference. If you expect a planned surgery that would hit the deductible, B costs at most $4,800 plus $1,500, or $6,300, against $3,000 plus $6,000, or $9,000, for A (before coinsurance). If you expect few visits, A costs less.
Where Pryme fits
Health insurance is bought in the US, not through Pryme. If you are also paying a parent's medical costs in Nigeria, a Pryme Personal Account keeps dollars and naira apart, and Send shows the rate and fee before you approve a payment home. See also health insurance for parents in Nigeria.
Questions people ask
Can green card holders buy Obamacare plans?
Yes. Green card holders are lawfully present and can buy Marketplace coverage, and they remain eligible for savings after the 2027 change if income and other rules are met.
Can H-1B holders get ACA subsidies in 2027?
HealthCare.gov says that from 1 January 2027 savings are limited to permanent residents, Cuban or Haitian entrants and COFA migrants, so H-1B holders can buy coverage but without savings.
When can new immigrants get Medicaid?
Generally five years after getting qualified non-citizen status, with some exceptions and state options for children and pregnant people.
Do I need health insurance as soon as I arrive?
No law in this guide requires it on arrival, but a single uninsured emergency can be very expensive, so arrange employer or Marketplace cover early.
