Financial preparation for overseas deployment starts with understanding the legal cost split: your service charge to us is capped at ₹30,000 + GST under Rule 25, paid digitally or by bank draft against a receipt.
Costs like visa fees, medicals and air tickets are the foreign employer's responsibility, not yours, under Indian law. If someone asks you to cover these costs yourself, that's a deviation from the standard legal structure worth questioning.
Budget primarily for the capped service charge and your own personal preparation costs (documents, any language coaching you choose to take) — not for fees that legally belong to the employer.
