Scheme.org micro-markup how to specify company branches?

Question

Google

There is basic information about the company

{
  "@context": "http://schema.org",
  "@type": "Corporation",
  "image": "https://www.example.com/logo.jpg",
  "name": "Intel Corporation",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "1600 Saratoga Ave",
    "addressLocality": "Moscow",
    "addressRegion": "RU",
    "postalCode": "123456",
    "addressCountry": "RU"
  },
  "url": "https://www.example.com/",
  "telephone": "[phone]"
}

1. The company has a bunch of branches in different cities and countries, how to add them to the microdata, phone numbers, addresses of these branches?
2. How else can I add hours of operation? "Corporation", "Organization" types do not have openingHours, openingHoursSpecification properties

,
  "openingHours": "Mo,Tu,We,Th,Fr,Sa,Su 09:00-22:00",
  "openingHoursSpecification": [
    {
      "@type": "OpeningHoursSpecification",
      "dayOfWeek": [
        "Monday",
        "Tuesday",
        "Wednesday",
        "Thursday",
        "Friday",
        "Saturday",
        "Sunday"
      ],
      "opens": "09:00",
      "closes": "22:00"
    }
  ]
