[Q] What is the most common misunderstanding people have about E visa consular processing?

One thing it should be noted about consular processing of E visas is that a different adjudicating consular officer can make a huge difference on whether your case will be approved or denied. Even though most consular officers decide E visa cases similarly, time to time, new consular officers get rotated to E visa cases for training purposes or other purposes -- which is fine -- but sometimes they really do not have sufficient experience and knowledge of FAM and regulations governing E visas. As a result, I have seen them issue totally weird denials. Therefore, it is very important for people to retain E visa attorneys who are very familiar with the particular American Embassy's practice. The only problem is that reviewing and adjudicating consular officers can change without any notice. As a result, same cases which have been approved previously by one consular officer (more experienced and knowledgeable about E visa cases) will be denied by another consular officer (who is not knowledgeable about E visas but may have been adjudicating F-1 student visa cases).
