Uzbek citizen with Kazakh residence permit entering USA [closed]

Legally speaking, yes, you would need a valid exit visa. Official source:

My own rough translation:

In accordance with Uzbekistan law, persons leaving the country for a temporary residence (business, employment, study, etc.) in a country which does not require the posession of a valid exit visa must request a new exit visa when visiting a country which requires an exit visa. Failing to fulfill this responsibility is a violation punishable by criminal law.

Kazakhstan is a country which does not require an exit visa and the USA is a country which does. Therefore you need a valid OVIR sticker. Anecdotal confirmation can also be found on Uzbekistani forums.

Note that Kazakh immigration is unlikely to allow you to leave the country, as the CIS treaty obliges them to check for exit visas in Uzbek passports. However the US authorities would have no issue with letting you enter the country, as long as your US visa is valid.

When you arrive at the US border no-one really cares whether or not you had permission to leave your country of origin or country of residence.

So the permission to leave the country of Uzbekistan is only applicable to Uzbekistan unless a treaty exists between the countries to check for such visas which I wasn't able to find between Uzbekistan and US.

Further. If you are a resident of Kazakhstan doesn't this mean that you already have a visa to leave Uzbekistan?
