What does this mean? I found this at the US embassy in Kazakhstan.
Does that mean there are certain amounts for K-1?
NUMERICAL LIMITATIONS
Whenever there are more qualified applicants for a category than there are available numbers, the category will be considered oversubscribed, and immigrant visas will be issued in the chronological order in which the petitions were filed until the numerical limit for the category is reached. The filing date of a petition becomes the priority date. Immigrant visas cannot be issued until an applicant’s priority date is reached. In certain oversubscribed categories, there may be a waiting period of several years before a priority date is reached. Check the Visa Bulletin for the latest priority dates.
