H-1B 專業職業專家意見書

We​ offer Expert Opinion Letters that can be used to support a variety of visa applications. They are used as supporting documents for a variety of specialized visas (EB, H-1B, H-3, L1, O) or other purposes.

It depends on the service, our current volume, and expert availability. Please see the order form for the service that you intend to purchase.

We offer guarantees related to the quality of our services, but we do not offer guarantees related to acceptance by the U.S. Citizenship and Immigration Services (USCIS).

For all Expert Opinion Letters and Work Experience Evaluations, we offer an uncomplicated guarantee of quality that we describe below.

• You or your lawyer may request certain modifications to your expert opinion letter, professional plan, or business plan within a time period noted in your service purchase. Within that time period, we will not charge you to make one update the letter based on the following types of modifications: errors of fact made by ProfVal or an evaluator, suggested wording changes, our omission of key details related to your case, or other factual changes that may help us to more accurately complete your evaluation. Subsequent updates or changes that alter the parameters of your letter may lead to additional charges.

​

• Please note that we will try to accommodate client needs, but will not make changes if we and/or the evaluator working on your evaluation disagree with the suggestions. For clarity, it is our ethical duty to provide high quality evaluations that we and/or our evaluators believe to be true. In fact, our contract with evaluators requires that evaluators agree to never provide an opinion that they disagree with.​

​

• For third-party services, please understand that your payment and service guarantees follow the requirements of those services. Any agreements with third-parties are in no way related to ProfVal.

​

It would be unethical and poor business practice to complete an evaluation inconsistent with an evaluator's opinion. Hence, we will only provide evaluations that we and/or our evaluators believe to be true and accurate.

​

If an evaluation request is submitted for a position and we do not believe that it meets our standards, we will provide a brief explanation as to why we feel this way. If we reject your case, we will return your payment to you minus a processing fee as expressed on your purchase page. This, however, is rare.

​

If you would like to receive a free assessment of your case and avoid this fee, please let us know more about your needs by filling out a form on our contact us page.

We are the best. Here are some of the reasons why:

​

• Attorneys tell us that the primary reasons they return to us relate to our customization and quality. They explain that other companies produce generic documents and prefer ProfVal's services because they represent high quality research documents that are customized to each client's needs and background. We think that providing each client with this level of service is the right thing to do.

​

• Our evaluators are the best. Before considering a professor or evaluator, we confirm their credentials and have high standards. Before completing an evaluation, all evaluators complete basic training with us. We provide feedback to all evaluators.

​

• Our prices often are better and we pay evaluators more. Based on our most recent market analysis (2021), our prices are lower than other companies that offer similar services. At the same time, we are not aware of competitors that pay evaluators as much as we do. Why would you go somewhere that costs more and pays evaluators less?

​

• We are small and care about you and our communities. ProfVal was started because our founder and his wife experienced the challenges of the US visa and immigration system. Although we do not provide legal advice, we provide assistance in a limited employment-based capacity to people who we believe add value to this country.

​

• We are a purpose-driven company. From day 1, our reasons for existence were to: offer the best evaluations on the market and to make a positive difference in the world. We donate some of our profits to our communities because it's the right thing to do. You can learn more about our pledge to social responsibility here.

​

Most of our evaluators, unless otherwise stated, are professors at accredited and ranked colleges and universities within the United States. You can learn more about our evaluators here.

Yes, and you can see that it is by looking at your search tab. When a site is secure, it sends a signal to your browser indicating that it uses an added level of encryption. If you click on our web address in the search tab, you will see that our web address is https://www.profval.com. The "s" in "https" stands for "secure". Depending on your browser, you may also see a lock on the left side of your browser, which is another way of showing that our site is secure. When a site is secure, it means that the data you upload is encrypted during its transmission, which matters most when you are on an unsecure network (i.e. a coffee shop).​

For payments, we always use a secure payment platform. We regularly use: Stripe, Square, and PayPal. We will only use platforms that are PCI Compliant, which means that they follow a series of security guidelines to comply with the Payment Card Industry Data Security Standard.

You should ask an immigration attorney for legal advice. We are not immigration attorneys. We can introduce you to an immigration attorney if you need legal advice.

Aligned with industry best practices, we or our partners may use technology tools (project/file management, email, generative AI, payment processing, etc.) to support processes in accordance with our strict privacy policy.

In some cases, technology tools may be used to assist in preparing documents, including to summarize content, ensure consistency, improving formatting, and more, but all documents are meticulously reviewed by professionals such as account coordinators, editors, and/or experts.

For any technology we use, we review their policies to ensure that the technology partners are keeping client data safe. As an example, we use Square and Stripe for payment processing. Both entities use PCI compliance to keep payment information secure, which means that not even we have access to your credit card information.
