Hindsight is a wonderful thing, however with a little preparation and research before you travel you can save yourself a great deal of hassle and upset, especially where visas are required.
A visa is an official stamp or document placed in your passport which will then allow you to legally enter, work, travel around and stay in a Country for the amount of time stated. Without the correct visa you will be denied entry, possibly forever in some cases.
This is a specific, non-immigration visa which is essential for any potential crew to hold if they wish to work on a luxury yacht which is either US Flagged Yacht and/or enters US waters.
B1 Visa = Visitor for Business
B2 Visa = Visitor for Pleasure
The Schengen States are 26 European countries who have signed a treaty allowing holders of a Schengen Visa to travel freely between them. The treaty was signed in Schengen, Luxembourg – hence the name.
These countries are Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and Switzerland.
Crewing on a luxury yacht will almost certainly involve you entering and travelling around The Schengen States, so obtaining a Schengen Visa, from the Embassy of the Country you will be first visiting, is essential.
