Shan and Vyoma Nair were the first to discover a strong need for a one-stop multi-country legal, HR, tax and accounting service to help technology companies expand abroad. With a keen interest in the multi-disciplinary interplay of issues (such as the need for  job descriptions to be consistent with the allowed activities of a subsidiary as specified in the US/local country intercompany agreement – HR and tax collide here), Shan and Vyoma launched their international consulting service in 1994 and grew this over time to more than 700 employees with offices in 6 countries and operations in more than 70 countries. Extensive practical experience gained in this consulting business is therefore distilled here into a unified knowledgebase of information you can access to get answers to a wide variety of questions, thereby saving you time and money. There are also several unique Playbooks that will help you plan and budget better! From legal entity setup to expat immigration, Shan & Co. is regularly updated to ensure companies have the latest information to operate safely abroad.
