Hi nauna,

You can now restrict Autocomplete predictions to only surface from multiple countries. You can do this by specifying up to 5 countries in the componentRestrictions field of the AutocompleteOptions.

You have use an array of Countries for componentRestrictions.

var options = { types: ['(cities)'], componentRestrictions: { country: ["USA","India"]} };

For more details refer below link.
