Operating Instructions
As the devil's advocate i present another detail ( it is always the details ) from Operating Instructions (Sweat the Small Stuff)
[p] From OI 245 Adjustment of status to that of person admitted for permanent residence.
Subsection
OI 245.4 Request for immigrant visa number.
a(6)
Subsequent Unavailability of a visa number. When a properly filed application cannot be completed solely because visa numbers became unavailable subsequent to the filing, the application will be held in abeyance until a visa number is allocated.
Those cases held in abeyance pending the allocation of a nonpreference visa number shall be periodically reviewed to screen out any applicant who appears eligible for a preference classification. Any applicant who appears eligible for a preference classification. Any applicant who appears eligible for a preference classification shall be informed and instructed how to proceed. IN all such cases held in abeyance pending allocation of a visa number, Form I-181, in duplicate, bearing the stamped notation "HOLD FOR VISA NUMBER" in the upper right-hand portion of the box labeled "For use by the Visa Control Office" shall be forwarded to the Visa Control Office" insure that a visa number will be allocated when one becomes available. Similarly, when a different preference is established, a new Form I-181 prepared in accordance with the foregoing shall be forwarded to the Visa Control Office. When a visa number is available in these cases, the Visa Control Office will return Form I-181 endorsed to show allocation of an immigrant visa number for the month following the month notification is furnished to the Service. This will allow sufficient time to complete any unfinished processing.
(c) (c) Disposition of allocated immigrant visa numbers. In each section 245 case requiring the allocation of a visa number, the Visa Control Office will endorse Form I-181 to show the allocation of the visa number. A number may be used at any time during the fiscal year for which it was issued. If the application is approved during that fiscal year, the date of acquisition of permanent resident status shall be the date on which the application is actually approved in a section 245 case.
If, after allocation of a visa number, the application is denied or it appears final approval will be delayed beyond the end of the fiscal year in which it must be used, Form I-181 shall be returned immediately to the Visa Control Office, conspicuously endorsed to show that the number is returned for cancellation.
Also, in order to eliminate the possibility that an allocated visa number will go unused and thus be wasted, whenever a section 245 case is to be transferred during the first 10 months of the fiscal year (October -July), after a visa number has been allocated and before a decision can be made, the office transferring the file shall transmit it with memorandum calling the attention of the receiving office to the fact that a visa number has been allocated for use in that year. When such a case is to be transferred during August or September, the office transferring the file shall first return Form I-181 to the Visa Control Office, endorsed to show that the number is returned for cancellation; and exception to this procedure may be made only if arrangements have been made telephonically or telegraphically to insure that the office is being transferred will adjudicate the application during the fiscal year in which the number must be used. If, after a Form I-181 has been returned to the Visa Control Office for cancellation of an allocated number, the applicant is subsequently found eligible, new Forms I-181 in duplicate shall be submitted to that office without a covering memorandum.
On the last business day of August of each year, a physical inventory shall be made of all pending section 245 applications to determine whether any allocated numbers have not been used. If an unused number allocated during the first 11 months of that fiscal year is found and the application cannot be immediately approved, the number shall be returned to the Visa Control Office no later than September 10 for cancellation. Special attention shall be paid to cases in which a visa number is allocated for use in September to insure that, if the case cannot be approval during that month, the number will be returned to the Visa Control Office at the earliest possible date prior to the end of the fiscal year to permit its possible allocation to another alien during that year.
Does this clarify....? Or confuse from the first post since this talks about Visa number not being available at the time of adjudicating the case. So OI (Operating Instructions) considers a practical scenario while maybe INA doesn't go in depth.
For all the coders, INA looks like a software spec and OI looks like the implementation (that probably does more that what the spec defines)....
