Was refused in UK, should I replace my passport? [closed]

Regardless of the answers to the other requests for clarification

Getting another passport will make exactly no difference to your situation.

Countries like the UK have sophisticated means of tracking your previous attempts to enter, and will definitely pick up on your previous record. The big X is to make sure you know what has happened, not to tell future immigration officers to refuse you entry.

• As DJCalyworth wrote, the UK will know even if you get a new passport. They keep records.
• Other countries might be told by the UK, or not. Depends on how good their information interchange is. It would be a really bad idea to believe that requesting a new passport makes that information go away. When asked "have you ever been denied entry" e.g. by the US or Canada you should tell the truth.
• That refusal notice will only matter when some official looks through your passport without a more detailed application in his hands. In that case, you would have lost the positive impression of a travel history to Italy.

Where a new passport won't help you:

• Hiding your refusal from UK officials
• Hiding it from countries that share immigration data with the UK (the Five Eyes)
• Hiding it from countries that ask about previous immigration issues in other countries (e.g. Canada)
• Getting into the UK again without a change in your personal circumstances (more on that later)

Where a new passport would help:

• Entering or obtaining a visa from countries that don't share immigration data with the UK and don't ask about immigration complications in other countries (e.g. Thailand)
• Boarding a plane to the UK or Ireland (airlines might refuse you boarding if they see a refusal stamp)

Therefore my advice is to replace your passport, but only after your personal circumstances change:

• Have a clear explanation of why you're visiting the country and for how long
• Have your finances in good shape, which normally means having a stable job or other source of reliable income
• Have strong ties to your country of residency - studying in Italy could be a good start
• Obtain a visitor's visa to the UK, instead of relying on visa-free entry. It is a recommended strategy for people who have previously been refused entry to the UK, as it will clear your immigration history.
