Applying for an L-1B requires more than just saying the employee is important to the company. File; It must also show the appropriate corporate affiliation, period of foreign employment, nature of the proprietary information, and relevance of the U.S. assignment to that information. The first step in the process is not to duplicate documents, but to determine whether these four headings are actually met. 1
1. Verifying corporate affiliation
U.S. and foreign company ownership, voting rights, and control structure are extracted. It is determined whether the definition of parent company, subsidiary, branch or subsidiary is based. Business contracts should not be used as a substitute for corporate ownership documents. 1
If there has been a recent change in companies, the actual structure at the application date should be taken as basis. If an old corporate scheme conflicts with new share records, this difference is disclosed. It should be understood which dated status each document shows. 2
2. Extracting foreign work and expertise history
The dates, duties and place of work of the eligible foreign work period are determined. The training, tasks or projects through which the person acquired specific knowledge are shown on the same timeline. Working time and knowledge level are proven as two separate elements. 1
Payroll and employer letter employment; Training contents, project responsibilities and technical records can support the content of the information. The function of the documents should be explained. A certificate of attendance provides limited information unless the advanced nature of the training is explained. 12
3. Explain why the US mission needs this information.
The job description should indicate where the person will use company knowledge. Instead of general “engineering support” or “customer management” terms, the connection of tasks to the product, process, or system is explained. Trade secrets do not have to be disclosed unnecessarily; but clear evidence must be presented. 1
The duration of the task, project phases and relationship with other employees must be compatible with the documents. Instead of exaggerating statements such as the applicant is responsible for the entire success of the company, the boundaries of his/her role should be shown. 2
4. Reviewing third party workplace layout
Control, supervision and scope of duties are particularly important for the employee to be sent to the customer site. The contract between the employer and the customer and the actual practice must show the same structure. A staff-only relationship should not be assumed to be an intra-company transfer of proprietary knowledge. 1
Meeting the customer's general personnel needs may differ from the implementation of the company's own product or system. The nature of the assignment should be explained in terms of actual work outputs and management structure. The title of the contract alone is not determinative.
5. Choosing individual petition or blanket procedure
The individual L-1B application is submitted by the eligible employer with the I-129. The blanket process can be evaluated in groups that meet certain size and institutional conditions. The presence of a blanket approval does not eliminate the personal eligibility of the employee; L-1B professional conditions are also reviewed. 1
Correct form version, signatures, fees and translations should be checked. The L base I-129 fee, eligible small employer deduction, Asylum Program Fee, and other applicable employer fees are calculated separately. A single total fee should not be declared for each file. 32
6. USCIS review and visa stage
Premium processing provides a 15 business day processing time for eligible L petitions; This is not a definitive approval or visa printing time. If the RFE comes, the requested element, existing evidence and the new statement must be linked together. 32
For a person outside the US, the consular and entry process is completed separately. If a status change or extension is requested from within the USA, current status history is reviewed. The periods on the approval document and the I-94 should be compared. 14
7. Task and time tracking after approval
A change of job, location, control structure or corporate affiliation may have an immigration impact. Not every change creates the same result; but essential changes should not be excluded from the case. The approved scope of work must be the same as the actual work. 1
In the extension, the current task, the company's activity and the need for specific information are displayed again. The total five-year limit must be calculated in time for relevant previous H/L periods and eligible overseas periods. If there is a permanent residence plan, it is useful to evaluate the separate process without leaving it to the last months. 15
