I just filed out eb- 1a with 140, haven't filed 485 yet , I have NIW which I prepared long time ago with everything done,just did not mailed out yet, for some reason. If I don't file NIW, I might need new reference letters for 6 or more , sine the last letters dated long time ago. should I file NIW now, , or should I wait for something for eb-1a come up? if I file 140 for NIW now, will it impact my 140 of eb-1a in one way or the other? especially they will be sent to same location ( processing center)? Thanks very much._
