"There is no simple answer to this question. It depends on various factors, including what country you are immigrating to, what type of visa you are applying for, and what information you provide to immigration officials.
Some countries do conduct surveillance on their immigrants, especially if they come from countries that are considered to be a security risk. For example, the United States has been known to closely monitor the communications and activities of people from Iran, Iraq, Libya, and Syria. However, it should be noted that immigration officials do not necessarily conduct this surveillance - it may also be carried out by other government agencies such as the NSA or FBI."
