Labor service information must be obtained first. Intentionally contact the labor service company, and then some things will be arranged by the labor service company. Then apply for a passport, and then have a simple physical examination. According to the requirements of different countries, some have to prepare innocence certificates and sign one or more contracts.

Submit the corresponding materials (original ID card, photocopy, resume, original passport, photocopy, technical level and professional title certificate). China citizens shall apply for passports or other travel documents when leaving or entering the country. China citizens who want to go to other countries or regions also need to obtain visas or other entry permits.
