Medical exams conducted outside the United States for those who are consular processing abroad are even more problematic. Staff at these facilities may aggressively question applicants about past alcohol or substance abuse, even in the far past, attempting to elicit a "confession" that can render an applicant temporarily or permanently inadmissible. Some reports state that even an admission to casual use of alcohol has led to the requirement of lengthy alcohol "counseling" before a visa can be issued. There is also an extensive inquiry into any tattoos that applicant may have as staff attempt to determine whether they represent gang affiliation. If you have any potential issues concerning alcohol, controlled substances, or tattoos you should speak in depth with an attorney to assess whether you can safely navigate this process and how best to handle any questions truthfully without creating unnecessary problems.
If you have objections to vaccines, discuss this with your attorney before advancing too far in this process. Although the law provides for religious exemptions they are difficult to obtain and require proof of a sincerely held religious belief. Objections not based on religion carry no weight at all. Pregnant applicants should also discuss the implications with their attorney to see how vaccinations and chest x-rays will be handled and whether it is best to proceed with the exam while pregnant or to wait.
