It takes 30 days to process a single form request. You can apply to travel to multiple countries with one A1 form and you can use the same form for up to 2 years. The best solution is a business travel tracking system. With this tool, you won’t exceed the specified number of days in any given country. If you exceed the predetermined days, you will no longer comply with EU regulations. If the business trip changes and more days need to be spent in a certain country, a new A1 form will need to be filled out. This will only supplement your previous estimates of the number of days to the current state. Please note that it may take up to 30 days for the form to be processed.
