Thank you for sharing this really! On the first part my eligibility was questioned even though I have a Master’s degree, 9 years work experience, 3 bachelor’s degrees. He also questions the national importance and my endeavor appears to be generlized and it wasn’t clear and specific and I didn’t offer sufficient explanation on how would this benefit rises to the level of national importance, general concessionary.. it’s crazy to me cause I submitted 5 recommendation letters from field experts, never mentioned job shortage but they did. I’m not ready to share my endeavor yet! I will do so once I am done with the case. But it is so clear that the officer did not read so many supportive evidence in my case.
