Health Insurance Checklist for New Immigrants: What to Buy During Your First 90 Days in the US? 

Moving to the United States is an exciting new chapter, but it also comes with many important decisions. Finding a place to live, opening bank accounts, starting a new job, enrolling children in school, and adjusting to a different culture can quickly fill your schedule. Amid all these priorities, one task should never be overlooked—obtaining health insurance. 

Healthcare in the United States is among the most expensive in the world. A single emergency room visit, hospital stay, or unexpected surgery can result in thousands—or even tens of thousands—of dollars in medical bills if you do not have adequate insurance. 

For many new immigrants, the first 90 days after arrival are a transition period. You may still be waiting for employer-sponsored coverage to begin, applying for Marketplace insurance, or deciding which long-term health plan best fits your family’s needs. Having the right insurance during this time helps protect both your health and your finances while giving you peace of mind as you settle into your new life.

Why Do the First 90 Days Matter? 

The first few months after arriving in the U.S. often involve several major life changes, including: 

• Finding permanent housing 
• Opening bank accounts 
• Applying for employment 
• Obtaining a Social Security Number 
• Enrolling children in school 
• Choosing healthcare coverage 

While newcomers manage these responsibilities, unexpected illness or injury can occur at any time. Having health insurance from day one can help reduce out-of-pocket medical expenses and prevent additional financial stress during this important transition period. 

What to do in the 90 Days? 

Step 1: Understand Your Current Immigration Status 

Your health insurance options depend on your immigration status, employment, state of residence, income, age, and other eligibility requirements. 

Examples include: 

Understanding your eligibility is the first step toward choosing the right plan. 

Step 2: Check Whether You Already Have Coverage 

Before buying a new policy, confirm whether you already have health insurance through: 

• Your employer 
• Your spouse’s employer 
• A previous international insurance plan 
• A university sponsored plan (for students transitioning to another status like F1 or J1) 
• A relocation package provided by your employer 

Buying duplicate coverage may result in unnecessary costs while providing little additional benefit. 

Step 3: Determine How Long You Need Temporary Coverage 

Many immigrants experience a gap before long-term insurance becomes available. 

Ask yourself: 

• Will my employer’s health insurance begin within the next month?  
• Am I waiting for Marketplace enrollment?  
• Am I still comparing permanent health plans?  

If the answer is yes, temporary health insurance may help protect you during the transition. 

Short-term coverage can provide financial protection against unexpected illnesses and injuries until comprehensive insurance takes effect. 

Step 4: Compare Your Insurance Options 

New immigrants typically have several types of health insurance to choose from. 

Common options include: 

Each option differs in eligibility requirements, monthly premiums, deductibles, provider networks, and covered services. 

Comparing several plans before enrolling can help you find the best value for your healthcare needs. 

Step 5: Review What the Plan Covers 

The lowest premium is not always the best choice. 

A quality health insurance plan should provide coverage for many common healthcare services, including: 

• Primary care visits  
• Specialist consultations  
• Emergency room treatment  
• Hospitalization  
• Surgery  
• Diagnostic imaging  
• Laboratory testing  
• Prescription medications  
• Preventive care  
• Mental health services  

The broader the coverage, the better protected you will be if unexpected medical issues arise. 

Step 6: Check the Provider Network 

Most U.S. health insurance plans use provider networks. 

Common network types include: 

• PPO (Preferred Provider Organization)  
• HMO (Health Maintenance Organization)
• EPO (Exclusive Provider Organization)  

Before enrolling, verify that: 

• Hospitals near your home participate  
• Your preferred doctors are in-network  
• Specialists are available  
• Emergency care facilities are included  

Receiving care from in-network providers generally results in lower out-of-pocket expenses. 

Step 7: Check Prescription Drug Coverage 

If you or a family member regularly takes medication, review the plan’s prescription drug benefits carefully. 

Ask questions such as: 

• Are my medications covered?  
• Is there a preferred pharmacy network?  
• Are generic medications included?  
• What are the copayments?  
• Are specialty medications covered?  

Prescription costs can add up quickly, making drug coverage an important part of any health insurance plan. 

Step 8: Make Sure Preventive Care Is Included 

Good health insurance is not just for emergencies. 

Preventive care helps detect health problems early, often before symptoms appear. 

Many comprehensive plans include preventive services such as: 

• Annual wellness visits  
• Vaccinations  
• Blood pressure checks  
• Cholesterol screenings  
• Diabetes testing  
• Cancer screenings  

Receiving preventive care regularly may improve long-term health while reducing future healthcare costs. 

Step 9: Know When Your Coverage Starts 

Not every insurance policy starts immediately after purchase. 

Depending on the plan, coverage may begin: 

• Immediately  
• On a future effective date  
• After an employer waiting period  
• During a Marketplace enrollment period  

Always confirm your effective date, so you do not experience an unexpected gap in coverage. 

Step 10: Keep Your Insurance Documents Organized 

Once enrolled, save important documents in a secure location. 

Keep copies of: 

• Insurance ID cards  
• Policy documents  
• Enrollment confirmations  
• Customer service phone numbers  
• Claim instructions  

Having quick access to this information makes it easier to receive medical care and resolve questions if they arise. 

Step 11: Learn How Claims Work 

Although many healthcare providers bill insurance companies directly, it is still important to understand how claims are handled. 

Take time to learn: 

• How claims are submitted  
• Whether preauthorization is required  
• How to read an Explanation of Benefits (EOB)  
• How to appeal a denied claim  

Knowing the process can help prevent delays and unexpected medical bills. 

Step 12: Prepare for Employer Health Insurance 

 If you will soon begin working, ask your employer about available health benefits. 

Important questions include: 

• When does coverage begin?  
• Can family members be added? 
• How much will premiums cost? 
• Which are the in-network doctors and hospitals?   
• Are  dental and vision benefits included 

 You may initially purchase temporary coverage and later switch to your employer’s plan once it becomes effective. 

Step 13: Review Your Coverage After the First 90 Days 

As your circumstances change, your health insurance should be reviewed as well. 

After your first three months, ask yourself: 

• Does my current plan still meet my needs?  
• Have I become eligible for employer-sponsored coverage?  
• Do I now qualify for a Marketplace plan?  
• Has my family size changed?  
• Have my healthcare needs changed?  

Reviewing your coverage regularly helps ensure you continue receiving the right level of protection. 

Common Mistakes New Immigrants Should Avoid 

Many newcomers make avoidable mistakes when purchasing health insurance. 

Some of the most common include: 

• Waiting until they become sick to buy insurance  
• Choosing the cheapest policy without comparing benefits  
• Ignoring deductibles and coinsurance  
• Failing to check provider networks  
• Assuming every prescription is covered  
• Overlooking exclusions and limitations  
• Missing enrollment deadlines  
• Not understanding their out-of-pocket costs  

Spending a little extra time researching your options can help you avoid expensive surprises later.

Frequently Asked Questions 

Do new immigrants need health insurance immediately after arriving in the U.S.? 

While there is no universal requirement for every new immigrant to purchase health insurance immediately, having coverage as soon as possible is strongly recommended because medical care in the U.S. can be very expensive. 

Can new immigrants buy health insurance before finding a job? 

 Yes. Depending on the immigration status and state of residence, you may qualify for an ACA Marketplace plan or be able to purchase private health insurance. 

Is temporary health insurance enough during the first 90 days? 

Temporary coverage can help protect against unexpected illnesses or injuries during a short transition period, but comprehensive health insurance is generally a better long-term solution. 

Should I wait for employer health insurance? 

If employer coverage begins soon, temporary insurance may help bridge the gap and provide protection until your workplace benefits become effective. 

How often should I review my health insurance? 

It is a good idea to review your health insurance whenever your employment, family size, income, or healthcare needs change, and at least once each year during your plan’s renewal or enrollment period. 

Conclusion 

The first 90 days after moving to the United States are filled with important decisions, and choosing the right health insurance is one of the most significant. Rather than focusing solely on monthly premiums, compare each plan’s benefits, provider network, prescription drug coverage, deductibles, and out-of-pocket costs to find the option that best meets your needs. 

Whether you’re waiting for employer-sponsored insurance, exploring ACA Marketplace plans, or purchasing temporary coverage, having health insurance from the beginning can protect you from unexpected medical expenses and provide peace of mind as you build your new life in the United States.
