The most difficult question in an L-1B file is often “Is this person knowledgeable?” but “What is the special or advanced nature of this information in the company context and how will the US mission use it?” is the question. The application must explain this connection with documentation rather than general praise. 1
A good evidence plan gives each document a specific role. The training record can show how knowledge was acquired, the project record can show how it was used, and the US job description can show why it was needed. The same document can support multiple elements; But no documents should be added just to thicken the case. 2
First, explain the subject of the information in a paragraph
The company's product or process, the applicant's knowledge, and the US mission should be able to be summarized in everyday language. If technical terms are necessary, their meanings should be explained. It should not be assumed that the officer has detailed product knowledge in every sector. 1
In the hypothetical example, instead of “he is an expert in our complex software systems”, it can be explained which module the person developed, which specific implementation steps he knows, and in which part of the US project he will use this knowledge. This is an example method of explanation; It does not mean that a particular software task will receive automatic L-1B approval.
Increasing the value of education enrollment
The name and duration of the training provide initial information. The record becomes more understandable if it is explained what skill the content teaches, whether it is basic or advanced, and in what job the person uses it. Certificate of participation alone does not always indicate the level of expertise. 1
In-house training material, module content, assessment result or instructor description may be appropriate. The same set of documents is not mandatory in every file. If there is no real record, a fake retrospective training file should not be produced. 2
Project documents must show personal contribution
The size of the project should be separated from the person's role in the project. The fact that the company serves a major client does not in itself indicate what specific information the applicant uses. Task sharing, delivered work, problem solving, or technical responsibility can be concretized. 1
If there is company secret or customer confidentiality, a meaningful statement can be prepared without sharing unnecessary details. However, when all content is obscured, there is a risk that the person's contribution will not be understood. A balance must be struck between confidentiality and provability appropriate to the case.
Making the comparison right
It is not a general obligation that the information be available only to the applicant. Conversely, the statement that “he does things well that everyone knows” does not meet the special knowledge standard by itself. If comparison is necessary, different task levels, learning stages and responsibilities should be based on real data. 1
Instead of immeasurable statements such as “ten times better than other employees,” describe experience developing specific processes, advanced problem solving, or implementing the company's particular system. If a numerical claim is used, the source and scope of the measurement must be specified. 2
Building a clear bridge to the US mission
There must be a concrete link between the knowledge acquired in the foreign company and the job in the USA. It explains which product will be applied, in which process the person will be involved, and what decision or technical responsibility the person will undertake. Past success is not a substitute for the quality of future assignment. 1
If the contract or project plan indicates that the U.S. mission is different, the wording in the support letter should be adjusted accordingly. The case should be prepared according to the actual task, not according to the desired legal result. 2
What questions should be asked in customer site documentation?
Who has control, who gives the work instructions, and is the task based on proprietary knowledge of the company? In the third-party workspace, these questions are important. Contracts as well as actual working order should show the same relationship. 1
There may be a difference between general staffing and the application of the company's specific product or process to the customer. This difference should appear not only in the title of the contract, but also in the scope of work and work control. 1
If RFE comes, is it enough to just send more documents?
It should be determined which element the RFE is questioning. If the nature of the information is questioned, simply adding the company's revenue may not be a direct answer. For each question, the existing record, the missing explanation, and the answer must be matched. 2
A subsequent training or assignment does not automatically carry back eligibility that did not exist at the time of application. The distinction between additional evidence and new relevance created subsequently must be preserved. The strongest answer is the one that meets the legal element asked with available and honest records. 2
