Germany has issued what appears to be the strongest recommendation anywhere for the mixing of Covid-19 vaccines on efficacy grounds.

The German Standing Committee on Vaccination (STIKO) said Thursday that people who receive a first dose of the Oxford-AstraZeneca vaccine "should get an mRNA vaccine as their second dose, regardless of their age."

This makes Germany one of the first countries to strongly recommend that people who have received a first dose of AstraZeneca receive either a Pfizer-BioNTech or Moderna vaccine as their second dose.

Another month another round of AOS submissions. Please be aware that this checklist is NOT all inclusive and you must consult the USCIS website to crosscheck this checklist against/with. The AOS process has been confusing since the pandemic hit, not to mention the added politics. So please I want to stress that you only use this check sheet as a starting point and guide if you will. The USCIS site will be the final guide. Please ensure that you check your forms for the correct versions and editions because if you use the wrong forms USCIS will reject your application and send it back to you. This is easily checked on the USCIS website prior to downloading your forms. You should also ONLY download your forms from the USCIS website. The current and correct fees can also be ascertained from the USCIS website

Be sure to double check for the current fees as fees do sometimes increase and they can change on a dime so please check. Additionally, check the forms as listed above i.e., current version and or edition date, there have been many changes to various forms. Consider sending tax transcripts instead of the 1040, and W2's. Also consider preparing a cover letter for each form in addition to the main cover letter.

Make sure you send long form birth certificates and not the short form. Hope this helps in your preparation of your AOS. When in doubt ask questions.

Please consider filing the I-131 and the I-765 even if you don't think you'll need them right now. You never know what changes your life will have on down the road, so I recommend you file these two forms from the start. There is no extra charge to file them with your AOS and it's better to submit them all at once. There has been much confusion coming out of USCIS, partly due to Covid-19 and partly self-inflicted. This confusion filters on down to the people filing for AOS. The above listing is subject to change at a moment s notice so please check, recheck and check again BEFORE you send off your packet for any last-minute changes.

Congratulations on a successful submission of your AOS packet!
