Visa Job Change Rules for Starting a New Job

A better offer can feel like a simple career decision. For a noncitizen worker, a visa job change is also an immigration event. The date you resign, the date a new employer files paperwork, and the date you begin working can each matter. Getting those dates wrong can create an unauthorized-employment problem even when both jobs are legitimate and the new employer intends to sponsor you.

The first rule is straightforward: your right to work comes from your current immigration status or employment authorization, not from an offer letter. Before you give notice or accept a start date, identify the category that authorizes your work and the action your new role requires.

Start with your status, not your visa stamp

Your visa stamp lets you request admission to the United States after international travel. It does not usually determine whether you can change employers inside the country. Your Form I-94, approval notice, employment authorization document, and status-specific rules are more relevant to a job move.

This distinction catches many people by surprise. An H-1B worker may have an expired visa stamp but still hold valid H-1B status and be able to change employers. Conversely, a person with an unexpired visa stamp cannot use it to work for a new employer if their work authorization is limited to the old employer.

Check the expiration date on your I-94 first. Then review your approval notice, EAD, and job details. A change in employer, job title, worksite, hours, salary, or duties may require more than a routine onboarding process.

H-1B job changes: filing can allow a start

For many H-1B professionals, the new employer must file a nonimmigrant worker petition before the employee can move. If you have already been counted against the H-1B cap and are maintaining H-1B status, the new employer generally does not need to enter you in the annual lottery.

Under H-1B portability rules, an eligible worker may generally begin work for the new employer once USCIS receives a properly filed, nonfrivolous petition. You do not always have to wait for approval. That can make an H-1B job change faster than people expect, but it does not make preparation optional.

The new employer still needs a certified Labor Condition Application and must file the petition correctly. The offered role must qualify as a specialty occupation, the wage must meet applicable requirements, and the job details must support the filing. If the petition is denied after you have started, your authorization for that employer ends. That is why some workers prefer to wait for approval when their risk tolerance, finances, or travel plans allow it.

Do not assume portability applies just because you once held H-1B status. It may not apply if you are out of status, have unauthorized employment, are changing from another category, or have a more complicated immigration history. Cap-exempt employers, concurrent H-1B employment, and moves between nonprofit, university, and private-sector jobs can add another layer of analysis.

You can resign from the old job before the new petition is approved, but the timing deserves care. An H-1B worker who loses employment may have a discretionary grace period of up to 60 consecutive days or until the end of the authorized validity period, whichever is shorter. A new petition should be filed within the applicable period. Do not treat the 60 days as guaranteed extra work authorization or a reason to delay planning.

Other work categories follow different rules

There is no single answer to whether you can begin a new job. Your category controls it.

L-1 workers cannot simply transfer

L-1 status is tied to a qualifying relationship between the U.S. employer and an affiliated foreign company. A new, unrelated employer cannot file an ordinary L-1 transfer petition for you. If you receive an outside offer, that employer may need to sponsor you in another category, such as H-1B, O-1, or an employment-based green card process where appropriate. Until you have authorization for the new role, you cannot work there.

TN professionals need employer-specific authorization

TN status for eligible Canadian and Mexican professionals is employer-specific. A new employer generally requires new TN authorization. Depending on citizenship and circumstances, that may mean a new petition filed with USCIS or a new application for admission at the border or preclearance location. Do not start the new position based solely on an offer letter or a prior TN approval for another company.

F-1 OPT workers must protect the employment record

On post-completion OPT, the work must be directly related to your major area of study. Report employment changes through the school’s designated official as required, and keep proof of job duties, dates, hours, and the relationship to your degree. Unemployment-day limits continue to matter.

For STEM OPT, the employer must participate in E-Verify and complete the required training plan. A new employer means a new training plan and reporting steps. You may sometimes start after the required process is completed, but timing rules are precise enough that you should coordinate with your designated school official before changing roles.

EAD holders may have more flexibility, with exceptions

If you hold an unrestricted EAD, such as one based on certain pending applications or dependent status, you may be able to change employers without a new employer petition. Read the category and expiration date carefully. Some employment authorization is dependent on a spouse’s status, a pending case, or a specific underlying condition.

A green card holder generally may work for any employer. However, someone who recently obtained permanent residence through an employer-sponsored process should understand whether the original job was offered in good faith and whether the facts still support that intent. Leaving immediately is not automatically prohibited, but it can raise questions later in a naturalization interview or other immigration filing.

Check whether the job itself has changed enough

A move within the same company can also require action. H-1B amendments may be needed for a material change in the terms and conditions of employment, including certain worksite changes. Remote work has made this less obvious, not less important.

Tell immigration counsel or your employer’s mobility team where you will actually work, including a home office in another state. Provide the expected salary, job title, duties, work schedule, and any planned client-site arrangement. Do this before the change takes effect, not after payroll has already moved you.

If your new job pays less, is part-time, or has substantially different duties, ask whether that affects the filing. A title alone does not decide the issue. USCIS looks at the underlying position and supporting evidence.

Protect your pay, tax, and benefits transition

Immigration authorization is the first question, but a job change affects your finances quickly. Compare the whole offer, not only base salary. Health insurance can have a waiting period, and your old coverage may end on your last day or at the end of the month. Confirm how you will cover prescriptions, ongoing care, and dependents during any gap.

Review the new Form W-4, state withholding, retirement match, bonus schedule, and equity terms. Moving from one state to another can change withholding and filing obligations. Your federal tax residency may also change over time under the substantial presence test, particularly for F-1 students and J-1 exchange visitors with exempt-individual days.

Keep your final pay stub, W-2, offer letter, immigration notices, and records of any moving reimbursement. You may need them for tax filing, future immigration petitions, unemployment claims, or a mortgage application. If you have a 401(k), decide whether leaving funds in the old plan, rolling them to a new employer plan, or using an IRA is appropriate before making a rushed choice. Cashing out can trigger taxes and penalties.

A practical checklist before you resign

Before you set a final start date, confirm these points in writing:

• Your current I-94 is valid and you understand the end date.
• The new employer has identified the correct immigration process.
• You know whether you may start on filing, must wait for approval, or need new admission to the United States.
• Your job title, duties, salary, hours, and work location match the information used in the filing.
• You have a plan for health insurance, payroll withholding, and any gap between jobs.

Keep copies of the receipt notice or approval notice once available. If you travel internationally during a pending case, ask qualified immigration counsel how travel could affect the petition, visa stamping needs, and your return. Travel rules are often the point where an otherwise well-planned change becomes complicated.

When to get individualized advice

A short consultation with a qualified immigration attorney is especially worthwhile if you have ever fallen out of status, have an employment gap, are changing from F-1 OPT to H-1B, have a pending green card case, plan international travel, or are moving from a cap-exempt employer to a cap-subject employer. Your employer’s lawyer represents the employer, so ask clear questions about your timing and keep your own copies of filings.

A job change should expand your options, not put your U.S. plans at risk. Treat the immigration timeline as part of the offer negotiation: ask what will be filed, who is responsible, and exactly when you are authorized to begin. That clarity is worth more than a fast start date.
