What documents can be submitted after filing the I-526?

You can make a choice to wait to collect the extra documentation before you file the I-526 petition, or file the I-526 petition now and expect an RFE. Please note that with either alternative a time delay will occur.

USCIS requires all relevant investment and project documentation to be submitted together. Not doing so would result in an RFE or denial. We recommend that you submit a full and complete package to USCIS.

It is highly recommended that you are qualified at the time of filing of your I-526. Your attorney should be able to tell you that. If you are missing critical documents, you will most likely receive an RFE (Request for Evidence) which will further delay the processing of your case beyond the average processing times taking longer than a year. The best practice is to submit all applicable evidence at the time of filing. You may try interfiling missing documents in the pending I-526 case, but there is no guarantee this will actually take place and you will not receive an RFE.

It is not a sure thing that documents filed late will be matched to the original filing - you can try.

You can try, but from experience you will probably be issued an RFE requesting the missing documents - but it is worth a try sending it in.

You must meet eligibility at the time of filing. If you meet eligibility, and the documents merely clarify, that is acceptable. You can also try interfiling, although that has limited success.

Naturally, it is preferred to have the complete application ready for filing when the initial application is filed. If this is not possible, yes, it is possible to submit documentation after receiving the Receipt Notice, but before receiving an RFE. This course of action may cause a delay in the case.

While it is best to submit the complete supporting documents along with the petition, sometimes it is necessary to submit a supplemental filing after the I-526. However, you run a risk of these additional documents not being properly filed with your other documents or being lost, as USCIS reported that it has received over 12,000 applications. Also, depending on how little documents were submitted with your petition, you also run a risk of the case being denied as being so incomplete as not to even bother with issuing an RFE. Finally, there is nothing we can do to prevent an issue of an RFE even if we think that we have provided all of the documents.
