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.
Processing times vary from application to application depending on volume and USCIS staffing capabilities. The time it takes to process a DACA application can range from 60 days in some types of cases to 27 months in others. Unfortunately, because this application was only just released, we have no idea how long it will take for USCIS to adjudicate them.
