When I arrive in the states with a K1 visa... I wait 2 weeks then apply for the social security number. Then I apply for the EAS and AOS at the same time? The EAS will run out while the AOS is pending so I will have to reapply... until the AOS is complete?

But as soon as I have a SSN and EAS I can apply for work?

We're really hazy about this whole thing.

You're correct - except the work authorization is known as EAD, not EAS.

Read the AOS and SSN guides again too, as a refresher.

if i recall right, the ead is good for a year, and if your aos isn't approved by then you'll need to apply for another one - nessa and i had to do that and the aos was approved one month after we spent $340 for the second ead!

I thought when they increased the application fee on the AOS they said you only have to pay once for the EAD card?

Currently, the I-485 fee is $325. The I-485 customer will also file, on average, two Applications for Employment Authorization (I-765) and nearly half will file at least one Application for Travel Document (I-131), while an additional 20 percent of applicants will file a second. These additional ‘interim benefits’ applications allow applicants to work or travel while their status application is pending. The combined fee that applicants currently pay is approximately $800. The proposed fee structure will eliminate instances for applicants to have to pay for these processing delays. USCIS is proposing a $905 fee for the I-485 form. In essence, the increase is $105 instead of $580; therefore, the overall weighted average is reduced to 66 percent because adjustment of status applicants will pay roughly approximately the same fee that is currently assessed when taking into account those associated ‘interim benefits’ that are paid over a multi-year time period.
