How To Get an Expert Opinion Letter Showing Your Experience And Education From South Korea

You spent years earning your degree in South Korea. You worked hard to build your career. Now you're ready to take your talents to the United States, but there's one problem. Will US immigration accept your Korean education and experience?

If you're applying for an H-1B visa, green card, or other work authorization, you might need an Expert Opinion Letter. This letter can make the difference between approval and rejection.

What Is an Expert Opinion Letter?

An Expert Opinion Letter (EOL) is a document written by a US university professor or recognized authority in your field. The expert analyzes your Korean education and work experience, then explains to the US Citizenship and Immigration Services (USCIS) how your qualifications match American standards.

Think of it as a translator for credentials. The letter shows immigration officials that your Korean degree equals a US bachelor's or master's degree. It proves your experience qualifies you for the position you're seeking.

When Do You Need an Expert Opinion Letter?

You need an EOL when your education or experience doesn't fit the standard US requirements. Here are common situations:

You don't have a 4-year degree. Maybe you completed a 3-year program or attended junior college. An expert can show how your work experience fills the gap. The standard rule: 3 years of progressive work experience equals 1 year of college education.

You're applying for an H-1B visa. These visas require a bachelor's degree or equivalent. If your credentials don't clearly match, you'll need an EOL to prove equivalency.

You received a Request for Evidence (RFE). USCIS asked for more proof that you meet the job requirements. An EOL provides that evidence.

Your degree field differs from your job. You studied business, but work in technology. An expert can explain how your combined education and experience qualify you for the specialty occupation.

You're seeking an O-1 visa or green card. These require proof of extraordinary ability. An EOL demonstrates your achievements and national importance.

What's the Difference Between a Credential Evaluation and an Expert Opinion Letter?

This confuses many people. Here's the simple breakdown:

Credential Evaluation compares your Korean degree to US standards. It lists your courses and grades. It states what US degree your education equals. Most people need this basic service.

The Expert Opinion Letter goes deeper. It combines your education AND work experience. It argues your case. It shows why you qualify even if your education alone doesn't meet requirements. You need this when standard evaluations aren't enough.

Many applicants need both a credential evaluation as a foundation and an EOL to strengthen their case.

How Does the Expert Opinion Letter Process Work?

Getting an EOL is simpler than you think. Here's what happens:

Step 1: You Submit Your Documents

You'll need your diplomas, transcripts, employment letters, job descriptions, and resume. The service reviews what you have.

Step 2: The Service Matches You With an Expert

They select a PhD professor in your field, whether that is computer science, engineering, business, healthcare, or whatever matches your background. You should see the expert's credentials before agreeing.

Step 3: The Expert Analyzes Your Qualifications

The professor studies your education and experience. They research your industry standards. They craft a personalized letter (not a template) that showcases your strengths.

Step 4: You Review the Draft

Good services let you read the letter and request normal changes at no extra charge. Avoid companies that won't let you see the letter before finalizing it.

Step 5: You Submit the Letter With Your Visa Application

The expert signs the final letter. You include it with your USCIS petition. The letter shows immigration officials why you qualify.

Most services complete the process in 5-10 business days. Rush options exist for urgent deadlines.

What Should You Look For in an EOL Service?

Not all services are equal. Here's what separates the best from the rest:

Real Experts, Not Templates

Your letter should come from an actual US university professor with a PhD in your field. The letter should analyze YOUR specific situation, not just fill in blanks on a form. Ask to see the proposed expert's resume.

NACES Membership

The National Association of Credential Evaluation Services (NACES) sets ethical standards for evaluation companies. Members follow strict guidelines. Foundation for International Services (FIS) is a founding NACES member with over 40 years of experience.

Transparent Pricing

You should know the costs upfront. Prices typically range from $500 to $2,000, depending on the visa type and complexity. O-1 and EB-1 cases require more documentation and cost more than H-1B letters.

Easy Communication

Can you reach them by phone and email? Do they answer your questions? Avoid services with no contact information or poor reviews about responsiveness.

Translation Services

If your documents are in Korean, you need certified translations. Using one company for both evaluations and translations saves time and hassle. FIS offers certified translation services in Korean and other languages.

High Success Rates

Check Google reviews. Look for real testimonials from actual clients. A strong track record matters when your future is on the line.

What Documents Do You Need?

Gather these items before applying:

• Your diplomas and degrees from Korean institutions

• Official transcripts or academic records

• Employment verification letters on company letterhead

• Detailed job descriptions for your positions

• Your current resume or CV

• Copy of your passport

• Any licenses, certifications, or professional credentials

If documents are in Korean, you'll need certified English translations.

Your Path Forward

Your Korean education and experience have value. Years of study at universities such as KAIST, Chungnam National University, and other respected institutions prepared you for success. Your work experience built real skills.

An Expert Opinion Letter helps US immigration officials see what you already know: that you're qualified for the opportunity you're seeking.

The dream you've worked toward is within reach. You just need the right documentation to prove it.

Ready to start? Don't let confusion about credential equivalency stop you from achieving your goals. Get the expert opinion that shows your true qualifications.
