Lanthanum is considered a rare earth metal because the process to mine it is difficult, time-consuming and expensive. Lanthanum is rarely the dominant lanthanide found in the rare earth minerals, and in their chemical formulae it is usually preceded by cerium. Rare examples of La-dominant minerals are monazite-(La) and lanthanite-(La).
If time is important, you should use Expedited or Rush Processing. Rush Processing (in states where available) Time to process your corporation or LLC formation varies by state with routine processing taking 4 - 6 weeks or even more in the slowest states. In states where it is available, Rush Processing will reduce the time to form your business to about 2 - 3 business days.
I think the average is somewhere between 3-5 weeks from biometrics to EAD-but, as said, it can be faster and it can take longer. I think there is some sort of a USCIS guideline that states that EAD should be issued within 90 days from when the AOS application was submitted, but it can take over three months as well.Most people here have the sigantures in the bottom of their posts, that's a fast way to see how long it has been taking. sent my AOS package (I-485, I-765 and I-131) on Feb 23rd, NOA receipt received on March 4th and just completed my biometrics on March 31st. My question is...how long did it take for your EAD to be issued after biometrics? I know each case is different so that's why I want to know.
