Nampech, the content of the attached invitation letter is little different than the one sent. It does not specifically mention that a multiple entry visa is requested. The USA visa contacts advised that the invitation letter should specifically mention that multiple entry is requested in order to be sure that it will be granted. The attached invitation letter is similar to the previous letter when a single entry Visa was granted instead of a multiple entry Visa.
Would be possible to add that a “multiple entry visa” is requested to the invitation letter?
