Expat communities have become genuinely useful career infrastructure, not just social clubs. In most major cities you will find groups that run practical career support: resume review sessions, often through volunteers who work in local HR or recruiting, workshops on adapting applications to local expectations, interview practice circles, and talks by immigration advisers and hiring managers. InterNations chapters, professional women's networks, chambers of commerce, nationality-based associations and industry meetups all host these in various forms, and some cities have dedicated career clubs for accompanying spouses, a group that faces particular reinvention challenges. Several governments even fund official newcomer career centers offering free coaching, worth checking in your destination.
The shared-experience layer is arguably more valuable than the formal programming. People a year or two ahead of you have already decoded what a local CV really looks like versus what guides claim, which recruiters answer, how interviews actually flow culturally, what salary a foreigner can realistically negotiate, and how they survived the demoralizing first months of silence, which nearly everyone experiences and nobody warns you about.
Use both layers: attend the structured events, but also just ask the group how others in your field cracked the market. The specific, current, unofficial knowledge in those answers is what no career guide can print.
