Relax pal. The 45-days letter means NOTHING. BECs are busy with entering all cases to the national backlog database and this process will take from them up to the end of summer. After that they will start real processing cases according to PD in each state. It means they will process all states concurrently and your case will be reviewed not early than the next year.
However I have one remark. All green card processing centers moved recently forward for all categories and their backlog significantly reduced for I-140 and I-485. The new I-140 in EB3 category did not arrive for last few months due to labor certification stopping in all SWA and probably new LC will not be generated up to the end of September 2005. It means that many present green card categories have a good chance to get 'current' processing time, for example Extraordinary Ability or Outstanding Researcher, because the processing time for I-140 in EB3 category is almost current and service centers will force to process all delayed I-140 and I-485.
However I expect one negative impact from PERM on backlogged RIR cases. Approved LC by PERM can generate a lot of new I-140 before your LC approval and you will stay in another line for I-140. It may take several years more.
It seems my lawyer was right, when he said half a year ago: "processing time for RIR will increase up to 4-5 years in NY state very soon". Total time to get green card (who submitted RIR in NY state) will be about 8-9 years. It is really big term and not everybody can stay with the same company for such long time. Many of us may not see light in the end of this tunnel.
