Here is some questions and answer related to EULT.
Question 1: I want to apply for EU Long Term Residency in Poland. But in the last 5 years of residency in Poland I was outside Poland more than 10 months. Can I apply for EU long term residency now?
Answer 1: No. You may leave Poland for any purpose for up to 6 months at a time, up to 10 months in aggregate within 5 years.
Question 2: I want to apply for EU Long Term Residency in Poland. But in the last 5 years of residency in Poland I was outside Poland more than 10 months as my employer in Poland have sent me in India for a company work Can I apply for EU long term residency now?
Answer 2: Yes. if you have stayed outside Poland because: – You worked, or accompanied (as a spouse or child) a foreign national working, for an employer based in Poland; – This was required by your personal situation (such as treatment that could not be taken up in Poland) and the interruption has not exceeded 6 months; – You served an apprenticeship or took part in activities required by your studies in Poland; this “absence” will count as a part of your residence anyway (considered as time spent in Poland).
Question 3 : How do you define a “stable and regular” source of income and a “sufficient income”? How are these evaluated as part of the proceeding for the grant of a permit for residence of a long-term EU resident? Or how many PIT 37 I need to submit?
Answer 3: This stability is tested for a longer period (2 years, if you are a highly qualified person that means you have EU blue card, or 3 years, otherwise, before your application).
So normally you need to submit the last 3 years PIT 37 as a source of stable income you had before applying EU long term residence permit.
