three stops · home → host → home · the third stop is where most assignments fail

Global mobility & expat management

A typical 3-year expat package costs $300K+ loaded. A typical assignment fails 20–40% of the time. Most failures aren\'t about competence — they\'re about family adjustment in the host country and a missing return plan when the assignment ends.

The journey, stop by stop

stop 01 · home — pre-departure

Family assessment, cultural training, role clarity, tax structure.

The single largest predictor of assignment success isn\'t the expat — it\'s their family. Spouse career support, children\'s education, cultural training, in-country mentor before they board the plane. Tax equalization vs protection decided here.

stop 02 · host — on assignment

First 6 months are highest-risk. Support reduces dropout.

Acclimatization isn\'t passive. Senior HR maintains a sponsor relationship from home, keeps the return role visible, runs quarterly check-ins on family adjustment. Expat communities, language support, and a buddy in the host country reduce 6-month failure rates by half.

stop 03 · home — repatriation

Define the return role before the assignment starts.

Most expats leave within 12 months of return because the company doesn\'t know what to do with them. The exam reliably tests this — the failure isn\'t at deployment, it\'s at landing. Without a repatriation plan, you\'ve invested $300K to train someone for a competitor.

tax · equalization

Tax-neutral with home country

Hypothetical home-country tax is withheld; company covers the host-country differential. Expat doesn\'t benefit from a lower-tax host, isn\'t penalized by a higher-tax host. Most common executive arrangement.

tax · protection

Capped at home-country burden

Expat pays no more than home-country tax — but can benefit from a lower-tax host country. Cheaper for the company in low-tax destinations; equalization is neutral. The exam tests the distinction.

Four assignment types — match length to need

Long-term (2–5 years): capability transfer, market entry, leadership development. Most expensive, fullest support package. Short-term (3–12 months): specific project, sometimes without family relocation. Commuter: regular travel between countries, family stays home. Virtual: remote work for a host-country employer — watch the Permanent Establishment trigger that creates host-country tax exposure for the company.

Exam Traps

Failure rates of international assignments are high

Documented expat failure rates 20-40%. Family adjustment is the single largest predictor. Senior HR addresses spouse/family before deployment.

Tax equalization vs tax protection differ

Equalization makes expat tax-neutral with home country. Protection caps tax exposure but expat may benefit from lower-tax host. The exam tests this distinction.

Repatriation is part of the assignment

Most expats leave the company within 12 months of return because of poor repatriation planning. Senior HR plans return BEFORE deployment.

Visa restrictions affect assignment design

Some countries cap business immigration. Some require quotas. Senior HR aligns assignment design with visa reality.

Family adjustment predicts success

The expat's family is the single largest predictor of assignment success. Spouse career support, children's education, cultural training reduce failure.

Plan repatriation before deployment

Define the role the expat returns to before leaving. Without it, repatriated talent leaves within 12 months.

1
Different climates

Each country has different employment law, tax, immigration, social norms.

2
Careful transplant

Pre-departure assessment, training, family preparation, role clarity.

3
Acclimatization period

First 6 months are highest-risk for failure. Strong support reduces dropout.

4
Cross-pollination

Expat brings home-country expertise. Returns with host-country insight. Knowledge transfer is value.

5
Replanting at home

Repatriation plan defines return role. Without it, expats leave within 12 months.

Greenhouse. Different climates. Careful transplant. Acclimatize. Cross-pollinate. Replant.
