Details worth checking

Ink Color and Legibility

Using an incorrect ink color or illegible handwriting can cause processing delays or rejections. Form I-129S requires all entries to be in black ink for clarity and legibility.

Accurate Organization Address

Providing incorrect or incomplete address information can lead to missed communications and delays. It's important that both mailing and physical addresses are accurately entered.

Complete Contact Information

Incomplete contact information can hinder communication and delay processing. Ensuring all contact fields are filled accurately is crucial for timely updates.

Attorney Information and Representation

Failing to include an attorney's state bar number or check the box for Form G-28 could cause representation issues. It is essential to provide accurate legal representation information.

Employment Size Information

Incorrectly reporting employment size, particularly regarding H-1B or L status employees, can affect petition outcomes. Accurate workforce data is essential for eligibility.
