Are there any restrictions on veterans going abroad?

It depends on what you want to do. There is no rule that veterans can't go abroad, like traveling abroad, but you can't settle in a foreign country because you will remain in the reserve for three years after you leave the army. When applying for a passport, it is very important to have a guarantor. If you explain the reasons for going abroad, if you are traveling abroad, you must have a travel agency guarantee. Otherwise, you must ... it depends on the specific position you hold. Senior officers who hold special secret positions or retire from active service can only go abroad after the prescribed declassification period. There are no restrictions for veterans to study abroad as long as they do not involve state secrets. Immigrants are generally unaffected. At present, I only see the document that "classified arms need to be approved by the original troops to settle abroad", that's all, there is no other explicit provision.
