You finally received it. The envelope from USCIS sits in your hands and inside is your H1B approval notice. But what does it actually say? What do all the fields mean? What do you do with it now? This guide breaks down the I-797 form field by field in plain English so you understand exactly what you are holding and how to use it correctly.
This is one of the most important immigration documents you will ever receive. Keep it safe. This guide explains everything.
What Is the H1B Approval Notice (Form I-797)?
The I-797, officially called the Notice of Action, is the document USCIS sends to confirm that your H1B petition has been approved. It is not a form you fill out. USCIS sends it to you. Think of it as the government’s official stamp of approval on your petition.
The approval notice goes to your employer first — or their attorney — because the employer is the petitioner. Your employer then passes it on to you. Keep the original in a safe place. If you lose it, you must file a formal request with USCIS and pay a fee to get a replacement. That process can take months.
Is the I-797 the Same as an H1B Visa?
No. This is one of the most common points of confusion. The I-797 is your approval notice. It proves that USCIS approved your petition. A visa stamp is a separate document issued by a US embassy or consulate abroad and placed in your passport. You need the visa stamp to enter the United States from outside the country. If you are already inside the US and changed status here, you may not need a new visa stamp right away — but you will need one if you travel internationally and want to re-enter.
The Different Types of I-797: Which One Did You Get?
There are several versions of the I-797 and each one means something different. Knowing which type you have matters.
I-797 (Standard Approval Notice)
This is the base version. USCIS sends it when it approves an application or petition. For H1B workers who are outside the United States, this version does not include an I-94 record. You will need to get a visa stamp at a US consulate and enter the country to get your I-94.
I-797A (Approval with I-94 Attached)
This is the version most H1B workers inside the US receive. It confirms approval of a change of status or extension of stay and includes a Form I-94 printed at the bottom. That I-94 is your proof of lawful status and the dates you are authorized to stay and work. This is the version you will most commonly deal with during extensions and transfers.
I-797B (Approval Without I-94)
This version is issued for alien worker petitions when the worker is not yet in the United States. No I-94 is attached. If you receive this, you must go to a US consulate, get your visa stamped, and enter the country before you can work.
I-797C (Receipt and Other Notices)
This is not an approval. It is a communication notice. USCIS uses it to confirm receipt of your petition, notify you of an appointment, or inform you of a case transfer to a different service center. When your employer files your H1B petition, USCIS first sends an I-797C receipt notice. That receipt notice contains your receipt number and is what enables you to start working under portability during a transfer.
I-797E (Request for Evidence)
This is not good news but it is not a denial either. USCIS sends this when it needs more documentation before making a decision. You have up to 84 days to respond. Do not ignore it.
Every Field on Your H1B Approval Notice Explained
Now let us go through the actual document section by section.
Receipt Number
Located at the top left of the document. This is a 13-character alphanumeric code. It looks like this: EAC-25-123-45678. The first three letters indicate which USCIS service center processed your case. EAC is the Eastern Adjudications Center (Vermont), WAC is the Western Adjudications Center (California), SRC is the Southern Regional Center (Texas), LIN is the Lincoln Service Center (Nebraska), and IOE indicates electronic filing.
You use this receipt number for everything — checking your case status online at the USCIS case status portal, responding to inquiries, and referencing your case in any communication with USCIS or your attorney.
Notice Date
This is the date USCIS issued the notice. It is printed just below or beside the receipt number. This date is important for calculating timelines. For example, if you need to file an appeal, the clock starts from this date.
Priority Date
This is the date USCIS officially received your petition. For H1B cap-subject workers, this is typically the date your employer filed the I-129 petition in April. For green card purposes, the priority date determines your place in the queue. If you are working toward permanent residency, protect this date carefully. It follows you even if you change employers, as long as your I-140 has been approved for 180 days or more.
Petitioner Name and Address
This is your employer — the company that filed the petition on your behalf. USCIS communicates primarily with the petitioner. If you have any issues with your case, your employer or their attorney is your first point of contact.
Beneficiary Name
This is you. Check this field carefully. Spelling errors here can cause serious problems at the border, during stamping, or during future filings. If your name is misspelled or does not match your passport exactly, contact your employer’s attorney immediately to file a correction.
Classification
For H1B workers, this field will say H-1B. Other common classifications include H-4 for dependents, L-1A for intracompany managers, or O-1 for extraordinary ability workers. Make sure this field matches your intended visa category.
Validity Period: From and To Dates
This is one of the most critical fields on the entire document. It shows the start date and end date of your approved H1B status. Your employer can only employ you in H1B status within this window. If your end date is approaching, your employer must file an extension before it expires or you will fall out of status.
Do not confuse this with your visa stamp expiry date. The visa stamp in your passport and the validity period on your I-797 are two different things. Your I-797 validity period governs how long you are authorized to stay and work in the United States, not your visa stamp.
Job Title and SOC Code
Your approval notice lists your approved job title and the Standard Occupational Classification (SOC) code assigned to your role. This matters. If your employer significantly changes your job duties — not just your title — they may need to file an amended petition. A material change in your role without an amendment can put your status at risk. Speak to an attorney if your responsibilities shift substantially after approval.
Wage Level and Salary
Your I-797 reflects the wage level and salary approved in the Labor Condition Application (LCA). Your employer must pay you at least this amount for the duration of your H1B. Paying less than the approved LCA wage is a violation of both immigration law and Department of Labor rules. If you believe your employer is underpaying you, speak to an immigration attorney. You have legal protections as an H1B worker.
Worksite Location
The approval is tied to the location where you work. If you move to a new worksite — even within the same city in some cases — your employer may need to file an LCA amendment or an amended H1B petition. Remote work situations have added more complexity to this. Always check with your employer’s immigration attorney before starting work from a new location.
The I-94 Section (Bottom of the I-797A)
If you received an I-797A, the bottom of the document contains your I-94 record. This is your official record of lawful admission. The date printed here is the date your authorized stay in the US ends. This date governs your legal presence in the country — not your visa stamp, not your employer contract. If you overstay this date, you begin accruing unlawful presence.
Always verify your I-94 online at i94.cbp.dhs.gov after every entry into the US and after every approved extension. Sometimes CBP records differ from what is printed on your I-797A. The most recent record governs.
What to Do After Receiving Your H1B Approval Notice
Check Every Field for Errors
Read the entire document the day you receive it. Check your name spelling, your employer name, the validity dates, your job title, and the worksite location. Any error — no matter how small — should be flagged to your employer’s attorney immediately. Corrections get harder over time.
Make Multiple Copies
Make at least three photocopies. Store the original in a secure location — a fireproof box or a safe. Keep one copy at home and one at work. Losing your original I-797 is a serious inconvenience that costs time and money to fix.
Use It at the Consulate if Traveling
If you travel internationally, you need your I-797 to apply for a visa stamp at a US consulate and to present at the port of entry when returning to the US. If your transfer petition is still pending, bring both the old I-797 and the I-797C receipt notice for the new petition.
Track Your Validity End Date
Set a calendar reminder 6 months before your I-797 validity period ends. Your employer needs time to prepare and file an extension. Do not wait until the last minute. Use H1BTrack.com to keep track of your H1B data and important dates.
Frequently Asked Questions About the H1B Approval Notice
What is the difference between I-797 and I-797A?
The I-797 is a standard approval notice without an I-94 attached. It is typically issued for workers outside the US. The I-797A includes an I-94 printed at the bottom and is issued when USCIS approves a change of status or extension for someone already inside the US.
Is my I-797 the same as my work permit?
Not exactly. Your I-797 approval notice confirms that USCIS approved your H1B petition. Combined with your I-94, it serves as proof of your authorization to work for the specific employer listed on the notice. You cannot work for a different employer based on this document alone.
My name is spelled wrong on my I-797. What should I do?
Contact your employer’s immigration attorney immediately. You will need to file a correction request with USCIS. Do not travel internationally with a document that has an error. Border officers compare your passport name with your I-797 and a mismatch can cause serious problems.
Can I work for multiple employers with one I-797?
No. Your H1B approval is tied to the specific employer who filed it. To work for a second employer simultaneously, that employer must file a separate H1B petition on your behalf. Only once USCIS approves that separate petition can you work for both companies.
What happens if my I-797 expires and my employer has not filed an extension?
You fall out of status the moment your I-797 validity period ends without a timely filed extension. Your employer must file the extension before the expiry date. If they miss the deadline, speak to an immigration attorney immediately. There may be options depending on how recently the deadline passed.
Do I need a new visa stamp when I get a new I-797?
Not if you are staying inside the US. Your I-797A and I-94 are sufficient to live and work in the US. However, if you travel internationally after your old visa stamp expires, you will need a new stamp at a US consulate before re-entering. Plan any international travel carefully around your stamp expiry.
How do I check my H1B case status using the receipt number?
Go to the USCIS case status portal at egov.uscis.gov, enter the 13-character receipt number from your I-797C receipt notice, and the system will show you the current status of your petition. For a full view of your H1B history and employer data, use H1BTrack.com.
