It is very important to provide documentation to show that the beneficiary is in legal immigration status if he or she wants an extension, change of status, etc. and is currently in the US. All H petitions, even those for extensions, must include documentation of the beneficiary's entire immigration history. Even if you have submitted such documentation previously, you need to submit it again for all subsequent petitions.
Beneficiaries/employees in the U.S. will provide
1) All pay statements from the start of the OPT until the present, rather than just 3 months of pay statements.
2) Letters from the employers that have employed the prospective H1B beneficiary during the period(s) of OPT, verifying the period of employment, that it was full time, and that the job was in the relevant field of study.
3) Any other evidence that confirms that the prospective beneficiary was employed full-time during the period of OPT and that the job was relevant to the field of study.
So far, this policy doesn’t seem to be applied consistently. Some petitions sent without this additional evidence have been approved but in some cases USCIS will send an RFE requesting this evidence. If you can provide the above additional documentation confirming that this prospective H1B beneficiary maintained valid F1 OPT status, we can include it in the petition and possibly reduce the possibility of receiving an RFE later, or even a denial of the petition.
Beneficiaries who are not in the US do not need to provide a copy of the I-94 card but should provide copies of passport pages. If such a beneficiary was ever in the US in F, J, or H status, the visa documents (H-1 approval notices, DS-2019s, I-20s and, if OPT was granted, the EAD card copy) relevant to those periods of visa status should be submitted.
